Not sure you do need cookies with photovucket, but sometimes it is worth a try....

if you jsut type in www.photobucket.com, and then type your user name in the white box at the top, what page do you then get?

What user name did you use BTW, so I can see what is happening myself? Might help me help you more.... Don't be worried you are giving out account info, as your username will be in every URL of every pic you upload and link to anyway, as are everyone elses who uses photobucket... It's you password that is sensitive....
