I got some pet buttons for my profile, but I -can't- figure out how to put them on it. Please help?

Uploaded them on Photobucket/Imageshack/OMGimages, did you? :) It's easy from there on. Just wrap the image with the link to the page you want to link to.
If, for example, you want to link to Greenbeans' profile, you'd use this code:
<a href=http://www.subeta.net/petinfo.php?petid=688928><img src=IMAGE URL HERE></a>
