I use imagestation with no problems. There are other sites that you can't link imagestation from but I just use a link there if needed. I know geocities doesn't work not sure about yahoo.
You could also click on the link in my signature...The Dis Photo Gallery provides hosting at no charge. Pictures can then be linked and used on our boards.
There is a new DIS site where you can load pictures and link them to here. It is a fairly new addition to the DIS, and all you need to do is sign up for it. If you are a site sponsor you get 10 times more space
