Photobucket having issues with Safari


I have a Mac Mini Mac OSX 10.4.11. I can no longer get into Photobucket, the page goes blank before I can even sign in. They said their having "issues" with Safari & suggested I try another browser so I tried Opera only to find it's not compatible with my Mac. I tried Camino but the same thing happened when I tried to get into Photobucket. What other browser will work with my older computer? Help
