Remove Dropbox from the gallery

well, i signed into my gmail account and deleted google photos there, so that solved the problem.
however, there are still two Picsa folders with a few pictures from my blog and if i delete those, i'm afraid they're gonna be removed from my blog too. yet, i don't want them to show on my photo gallery on the samsung galaxy s. any ideas?

edit: i take it, i'm either the only one with this issue, or nobody really knows how to fix it.

DANG!  i was hoping there was a resolution... I'm having the same "issue" ... sort of... I've never created a "Drop Box" account, but suddenly one day I have a pic show up on my gallery from 3 years ago!!!  and I shows that it is in my "Drop Box" album... which i don't have!!  and it won't allow me to delete it...

grr...

anybody???
