Eva, in a book (2006) that I have for profile layouts there is a list of Image Hosting Web Sites. They used Photobucket for the examples, so I just signed up for that one. I've bookmarked these...just in case Photobucket should go away one day. I'm sorry that your favorite site is gone. Maybe one of these will be right for you. I checked and all are still active. Here are the links, in no particular order, and what was said about each back when the book was written:
