PHP Image Gallery

I know there are a ton of these out there and I've used a few of them, but I'm looking for a specific feature, of course. :) Does anyone know of a Gallery system where I can, once it's installed, just drop a folder full of images into the "gallery_root" and the program automatically makes it into a new "gallery" on the web site. In other words, I don't want to go through and Browse... for each and every file. Any advice is greatly appreciated. Again, I already know what gallery program you use (I'm psychic ;) and I agree with you that it's the best program out there, but does it have the above feature? ---John Holmes...
