Unfortunately I don't use AOL myself and I can't tell you how to do it on AOL's browser. I'm certain there is an option for deleting cookies from within the AOL browser but I don't know exactly where.
I'm sorry you are not happy with the site and caused you to get upset. We work very hard to make everything as easy and as usable as possible. Our pictures section didn't go "bad". It simply grew too large so that we had to move some of the old pictures. All the old pictures are still there. You can find them at this url:

The reason things can't just "stay the way they r" is because the site is constantly growing and continually get more and more hits. As such we have to change things and adapt to accomodate the higher load on our servers. Rest assured we are always doing everything we can to make things run as smoothly as possible.
As for deleting your cookies, this is only something you have to do once. Once you've done it you'll be able to log out as usual again.
