The photobucket App only uploads them, it won't delete them, at not that I see in the settings and they never disappear off my phone.
What apps have you got installed ? One may be doing similar to what Deicer boy said.
Less of the cocky tone, it sounds like you think something of yourself.

I was simply suggesting by some miracle if the app was on the phone could be on Photobucket.
Plug the phone in and look on the memory card for the files.
I strangely enough had the exact same thing for the first time today. Couldn't see pics I'd just taken for the MK3 game in the MK3 forum. Plugged it in, they were there. Now I've unplugged it and its "prepared the SD card" and can access them on the phone.
