Ok, Wookie, just do as Nemitor said;
1) Find an avatar you like. (The site has many avatars preloaded if you want to choose one of those instead)
2) Get the link url (Right click the image, click on properties, then copy-and-paste the link url)
If you don't know what I mean by a link url, the url for my own avatar is
http://img.photobucket.com/albums/v207/ ... sports.gif
It should look something like that. You should probably check about file permissions as well, coz not everyone likes people linking to their own work. If you make your own, you can avoid problems like this.
3) Log into this site, and click on "My Account".
4) Click on "Change Info".
5) Near the bottom of the page, you'll see your current avatar (The question mark one) next to a blank text box. Paste the url link into this box. (Or click on the "Show Gallery" button if you want to choose one of those)
6) Select the checkbox to delete the current image.
6) Click save changes.
If you decide to make your own avatar,
Photobucket and
Imageshack are both excellent free filehosters. I personally prefer photobucket, but you have to register with them before you can upload stuff.
Just copy the links they give you once you've uploaded your file, and enter this link into the text box that I mentioned in step 5.
General Avatar rules
Although the site has rules on the sizes of avatars, these are not strictly enforced. I myself am breaking these rules, as are about 90% of the other people on the site who have custom avatars!
However, please try to keep your avatar as small as possible. The max width (In pixels) should be no more than 150. This avoids messing up the post sizes in the threads. My own avatar is exactly 150 pixels wide, so if your avatar is bigger than mine, resize it!
Try to keep the space size as small as possible as well. Remember, everytime a page is loaded, you have to download the avatar. This can really slow down the speed that a page loads up, especially for those on Dial-up.
If you are using an animated .gif as an avatar, then optimise it. This can save quite a lot of memory. (And therefore load time) You won't encounter this probem with a static image.
