I was used to using Photobucket. I liked it because the way it generated code for embedding was easy for me to understand. I'm pants at coding. That's why I stayed with them despite the spam ads hijacking the entire screen and requiring closing and reopening with some frequency. I am happy to deal with ads if that makes a service free. Folks need to make money, after all. But it seemed like some site hijacking was going on, not only usual ads. I don't mind paying money for a service I enjoy using, but balked at spending so much money for a website that seemed to me to have a few serious issues. Just my opinion, of course.
So I took down all my pics, and switched to Postimage.org. This site seems the closest to Photobucket and it is also very user friendly.
