Yeah, all sorts of weirdness. After deleting the image (which shows fine in the profile page), uploading a smaller, different .jpg, it somehow took the original deleted file, and shrunk it to the size of the newly uploaded file. Still wouldn't display on a post, only on the profile section.
And links to Photobucket don't work at all (for me). Its as if the link is totally ignored. Have checked out a dozen or so other member profiles/pic links, and they work fine, even though the format is exactly the same as what I've been trying.
Something may eventually work....
