I don't know why it's not accepting the URL. Like, I've done it from the Phototbucket copy to clipboard function, using each of the four options (only the direct link should work), and that gives a Photobucket site image (like, "click this to go to photobucket!"). Otherwise it's a broken image. Viewing the image and copying that url also is a broken image. So if I can fix it to Photobucket it'll be permanent, which is better. I shouldn't have to need a new hosting site.
