Bitpim Help!

Haha, sorry guys, i've been posting various posts everywhere about how to do this and how to do that...
but i'm curious:
i've started to use bitpim and it's FABULOUS.
the thing is i've added a wallpaper/picture through bitpim, and when it restarted, the picture was successfully there, but all my pictures were scrambled everywhere and when i checked the info of the pictures it had no date and time when the pic was taken.
question is:
is this supposed to happen?
is this something to be concerning about?

you're answers are GREAAAATLY appreciated
thanks again!
