Copy all pictures from Dropbox to Backup folder.

I want to create a rule that copies all my images (.jpg, .png. and .gif files) in dropbox (so with all the sub and subsub folder) to the backup images folder.

I have got this working but it also copies the folder and i just want a clean folder only with pictures and no folder in it.

So you want all your images together in one folder? I can't say for sure without seeing your rule but my guess is that you are incorrectly using the "any of its sub-files" target. If you want Hazel to go into subfolders, you should not use that, but instead follow the sticky article near the top of this forum.
