I'm not noticing any problem in Photobucket running Windows-7/Firefox with Addblock+ on a wired cable-modem
Did a trial, connected my phone to the PC Logged into Photobucket chose an existing album & clicked upload, had to browse through my phone to find the picture I was looking for then selected, uploaded, saw it was sideways, selected edit & rotated, saved, copied URL & pasted here inside of 3-minites..
One more thing, I selected my largest album, 191 images, it loaded in 5-seconds then a random page which loaded in 2-seconds...no lag I'd say
