I guess I'm missing something. When I want to copy all the photos from my website to my hard drive or from a folder to my hard drive, or vice versa, I just load an FTP program, navigate to whatever folder and in a few clicks the photos are all on the way to my computer. Any FTP program will give this ability and it will work on both Unix servers (about 80% of the server base) or Windows platforms.
I might mention that you should carefully check your app to be sure there are no security flaws as these kinds of programs can often leave holes in your server's defense against hacking.
