****** THIS HAS CHANGED, SEE OTHER THREADS FOR THE NEW WAY OF CHANGING YOUR BACKGROUND *******
This is one of the features I like a lot on this site. You don't need to enter any codes like myspace either, which is great cause i always messed that up!
Anyways to change your background image just go to your profile (you have to click on the "Profile" tab), then after you do that just "hover" over the profile tab again (without clicking on it) and you will see 2 new links in there. One is says "change background" and the other says "Change font color".
I recommend that you do the background first, then change the font color to suit the backgound
CHANGE BACKGROUND
Click on the "Change Background" link
Now you can choose from the menu to either use a gallery image (this is autumnslist's gallery) or upload your own image. You can also just use a color without a image, Do this by clicking on the little color wheel.
if you upload your own background make sure you hit the "upload" button. When you hit that button it will automatically upload it and you will see it right away
now once your done with your image click the save button, then go to the change font link and adjust your font color so people can actually read the words on your profile page! to do this just click on the little color wheel, find your color then click save settings.
oyea you can see your colors on your page as you pick them, just scroll down a little each time you pick a new color and you will see what i mean
Have fun cause i kow i am
