I really think Facebook should give this hint up front on the photo upload page, and maybe even point you to some helpful tools. You see, as far as I know, the pictures you and others post to Facebook are only stored on Facebook servers in the size you see them. Often enough, though, the original pictures uploaded are bigger than this. Thus, uploading time is wasted when you could just upload the right sized pictures in the first place. The Picasa Facebook plugin does this, for instance, allowing pictures to actually be uploaded using dial-up. Woot!

To the point, the maximum width your photos are displayed at on Facebook is 604 pixels, the maximum height being 604 also. If you're uploading anything smaller than that, don't bother resizing. But if they're bigger than that, you can save some time. So, use your favorite program to size your photos down to this width or height. Or if you have no idea what to use, try Fotosizer for Windows and RapidoResizer for Mac. Linux users, figure it out (you're supposed to be smart).

And as a side note, I think Facebook should seriously add a real yearbook view, where you could view a spread of thumbnails of your friends, since that's what it's named after (yearbook/facebook - see the connection? Check this ZDNet definition for full info - it's actually a bit different take than I have, and in fact I guess I'm wrong about what it's named after, but I still think a yearbook view would be cool).

P.S. If you have a free Flickr account, the max size your photos will ever be viewable at is 1024x768 pixels, I think (and as I remember, I think you might even have to turn that size on). So, you might be able to save some time the same way there.
P.P.S. I'm wondering if your photos are somewhere on the Flickr servers at a larger size than 1024x768 even if you have a free account - maybe if you upgrade to pro, you could get access to these bigger versions. Just speculating. Take the Flickr tip at your own risk.

Edit: July 25, 2009: I re-registered for Flickr today and contacted them about the original file free account to Pro thing. Speaking about Flickr free, I was told this by Natalie at Flickr Customer Care:

Only smaller (resized) images accessible (though the originals are saved in case you upgrade later).

Bingo. Just what I wanted to know. So upload at 1024x768 with that knowledge - if you go Pro, your photos will only be viewable at that resolution max. So, if you think you might go Pro in the future and think this could be an issue, upload accordingly. I personally plan to upload at 1600x1200 or widescreen equivalents, because that's what I've been doing with my photo blog to save upload time (and download time for viewers, now that I think about it).

Edit: July 27, 2009: I just found a way to get at the originals with a free Flickr account. Who knows how long it might last, but here goes (might make a post out of it later). It's the photostream RSS feed (I haven't tested Atom yet). Just stick it into a feed reader that supports attached media (including Firefox's Live Bookmarks) and grab that attached media. It appears to be the original. Test it out right here on my RSS feed. I'm suspecting that maybe Flickr doesn't mind as much about this, but they just make it easy on Pro and call it a Pro feature. In fact, they start you on your way to finding the originals over here by documenting the photo source URLs.

Because of the ever expanding world of social networking some people complain about just another thing to update. I quite concur… if you have say five different services you want to post the same message to, it can be a bit of an annoyance. Or a drag. Or whatever you care to describe it as. However, I think that that problem could be at least partially solved by the use of services such as Ping.FM, an online tool that lets you update many services at once (though I have never used such a service… yet).

But, that's not what I do. I have a few services I have joined over the years, and in my mind I have a purpose for each. And here they are:

• Blogs (my current platform is Blogger): for posting longer stuff… sort of textual works of art sometimes: discourses, arguments, current events, reviews, etcetera. Also, questions to the masses, guides, longer write-ups on personal life and experiences, and so on. Or sometimes, just less formal stuff and perhaps shorter stuff.
• Twitter: for microblogging, as the service is described. Short things I want to say or just whatever I want to say; sometimes randomness or seemingly such. Also, it's good for plugging in updates and notices from stuff, like twitterfeed (pulls feeds to a Twitter profile). Also, I like that it's microblogging… it's limited to 140 characters, so it can make you be creative. It can be the art of brevity.
• Facebook: a great all around social utility for me. Text, images, and video are supported, so any such things may be posted. And what's alluring about this is that it is a sharing just within your circle of friends, not public (though I think you may choose to do so… I doubt many users do). It's very pluggable-in, which I like. You can post and link to your heart's content, and it's really popular with some people, which can make for perhaps the most effective means of communication to some people. Also, it has a community aspect within the privacy; many interactions between can be publicly seen by their circle of friends, who can easily join in. And, back to the pluggable-in aspect, there are many, many Facebook Apps, some of which plugin in to other services, or let other services plug into Facebook. And by the way, if for any reason you got confused, it's Facebook, not FaceBook.
• Delicious (previously called Del.icio.us): It's social bookmarking. Personally, I'm not too into the whole see what's up on Digg or Delicious thing, but it works good for putting a linkroll on my blog, so people can see what I've recently bookmarked, thus I share it with them. I use the bookmarklet, which works great for bookmarking pages I want to share. Also, it can create a record of where you've been on the web of sorts… not a strict statistical or analytical record, but a sort of what-I-thought-the-best-then collection. And you can add your comment to stuff you bookmark, which works with the collection idea. Not to mention if something isn't any longer in your browser history and you want to find it, maybe you bookmarked it on Delicious (or Digged it, for that matter). As I said at first, I'm not really too much into the see-what-floats-to-the-top idea, but maybe I would be if I had a better internet connection. I guess we might see in the future.

So that's what I use. How about you? What's your social networking philosophy? Or do you even have one?

Update, March 30, 2009: I updated the post to note that the Vista folder is in a bit of a different place. Also, I found out today that version 2 of the plugin was released in January. And I didn't even notice until when investigating the Vista path via my bro on his Vista laptop, I saw the file name and the extension of the plugin was different and that he actually had a Facebook icon in his Picasa. Also, the new version seems to install fine automatically (just a couple of boxes to click through). I did a small test and it seems to work fine using my Picasa 3 installation. The new plugin is for Window/Mac Picasa 2 or 3 (still no Linux, augggg!). The old version of the plugin seems to be working, still, and is still downloadable by the address I specified in the post (as of 03.30.09) so if anybody wants it, get it there; if that link goes dead, I uploaded it here. Oh, and I couldn't say anything about manual installation of either plugin on a Mac... sorry, I don't own one and don't feel like chasing down the correct folder. /end of update

The Picasa Facebook plugin is brilliant. There is a Linux version of Picasa, too, but unfortunately, the plugin only works with the Windows (and now Mac) version.

It downsizes the images in Picasa and uploads them to Facebook, which makes it tons faster. Pretty seamlessly. Which is nice, especially if you're on dial-up. And a great solution for anyone, considering you can't download the full size images off of Facebook anyway (not as far as I know).

I would just link and leave if that was all there was to it. Unfortunately, I had to manually install the plugin. There is a installation button on the Facebook page, but it doesn't work (at least for some people). So, I knocked together a guide in a Facebook note. This is the rewrite. Please note, although I have heard the plugin works with Picasa3, this guide is for Picasa2. It may or may not work for installing it in Picasa3. I don't know. If anyone has info on this, please tell me.

So, if the installation doesn't work automatically for you, follow these instructions. These are for XP, but pretty much the only difference in Vista is that the folder to put it in is different:
C:\Users\[your username here]\AppData\Local\Google\Picasa2\buttons\

1. Have your web browser running
2. Paste http://www.webkinesis.com/fbpicasa/facebook.pbf into a new tab or window and go or just follow this link
   For version 2 of the plugin, http://www.webkinesis.com/fbpicasa/packages/v2/facebook_v2.pbz or link
   
3. If your browser asks you what to do with the file, choose to save it and select whatever location you want (don't forget where, though)
4. If your browser didn't ask you what to do with the file, you should be seeing what is actually the content of the file. It's a bunch of text. If you don't understand it, don't worry, it doesn't matter. Just save it like you would a webpage (File > Save as or Save Page As) to wherever you like.
5. Now, we have to put the file in the right place. Copy the file first.
6. Open My Computer. Open C:\Documents and Settings\[your username here]\
7. Now, you're going to have to have hidden files visible to continue (Tools > Folder Options, View tab, Show hidden files and folders, OK)
8. Now open \Local Settings\Application Data\Google\Picasa2\buttons. (So now you're in C:\Documents and Settings\[your username here]\Local Settings\Application Data\Google\Picasa2\buttons)
9. Paste facebook.pbf into this folder
10. Now, open Picasa
11. Open the Tools menu and select Configure Buttons…
12. On the left side will be your Available Buttons, on the right side your Current Buttons. Find the Facebook button on the left, select it, and click Add>>
13. The Facebook button will appear with your other buttons on near the bottom of the Picasa window.
14. Select some pictures, click the button, follow the prompts, and enjoy! Keep your eyes peeled: there should be a link at the bottom of the window that appears at some time, offering to let you enable Extended Access (it's a Facebook thing). Do it. Otherwise, you'll have to approve all photos you upload from Picasa on Facebook itself before they are published. That's a drag.

Notes: if you're not a power user, you probably will want to turn off hidden files. Just follow the same steps you used to turn them on, except this time select Do not show hidden files and folders.

Feel free to ask questions and otherwise comment.
