copy files without directory structure

Hi - I've set up a rule to copy iCloud photo stream images to a target directory, so that Adobe Lightroom can import them. My rules are:
Source folder = ~/Library/Application Support/iLifeAssetManagement/sub (which contains a number of subfolders each containing an iCloud Photostream image)
Kind is Folder
Run rules on folder contents
Copy to folder <my target directory> with the options if file exists, do not copy the file and do not copy if duplicate.
Copy folder structure is *not* selected
When this runs, the subfolders are copied as well as the image files inside them. I want to copy just the image files over to the target directory, not the subfolders that they're contained in.
Is there a way to do this in Hazel?
Thanks!
