you first of all have to open the picture up that is in your album and copy the picture url thingy and paste it in the customise profile section under the heading 'background image'- hope that makes sense
if you upload your own, then after you do so you click on the little icon next to the text box under "background image" and there should be a thumbnail there
so when you're in customize profile, under the heading -main- you'll see "background image". you can either find something on the internet and copy the URL address in the little text box or upload your own on BOS albums
so you're in customize profile, then you copy + paste the URL of your image you want to insert as the background.
You can make your own and upload it in your album on BOS or find a pattern through google and just copy the entire address bar
ohhh well it would be better if it was 777!
when it's 777 then that will be your lucky day
Welll here is the test to see if you are really awesome at explaining things- i will try and put up a background and if it works then you are awesome! haha
