Recovery of deleted files?

Good evening, this is my very first thread here so hope nothing goes wrong.. anyway.. today by accident (yes i know it sound silly/dumb) i deleted one of my picture folders, and would like to know.. if anyone of you know some kind of trick that could be useful in anyway?

i already found one program that was able to recover files(Restoration) the thing is just, it's not all that is intact..:/ some of the pictures get recovered, but just as blank..?
(and yes, i'm sure they are not just in the garbage can) (also..i did some research on how the whole recovery progress works, and i'm already now, not saving something ontop of the old data)

i'm kind of desperate here and any help whatsoever would be greatly appreciated.. thanks in advance:)
