Yeah photobucket acts up for me sometimes too. Usually works the second time around. Pain in the ass all the same!
I was trying on the 22nd to upload stuff, but it wasn't working, so I just assumed it was having one of it's off days. But alas it's still being a spaz, so I'm back to using it on ie, as it's not spazzy on ie, only on firefox.
I had the exact same issue last night. It must have been universal. So annoying! That's the first time I didn't update my blog until the next day.
