Lost user - remove folder structure

Hello
I've a bunch of images that are organized by year -> month - >filename
like
2012
....01
....02
... etc.
I'd like to take all the image in those various years and month out and have them in a single folder - moreover, the file names are like this: 20110501-052830.jpg - those are the main files and I like to move or copy only those to a new folder - some other images are all named like: 20110501-052830-600x270.jpg . those can all be ignored. so the end result I'd expect would be have all the main images in one single folder - preferable a copy.
Hope somebody can help to get me going - whatever I try just doesn't work the expected way.
Thanks
