how do you add a photo???
if you want to add a photo (avatar) just make or choose a picture, go on photobucket.com, make a account and submit a photo. after it will say a link under the photo copy the link and go to your control panel on this site. click 'edit avatar; paste the link and update your avatar.
If you want to insert a picture (sprites for example), use photobucket.com or imageshack.us as an image hosting site. Then click the image button when posting (img), and paste the link.
