620 SIMPLE photo gallery

I need a photo gallery, that will scan that same folder in which the file is located in, for images (GIF/JPEG/PNG). So it needs to scan that same folder, and genereate thumbs, which are clickable, which will open a popup using Lightbox, and on top of it, should have a option to control the gama. Also I need it to have a the following options, 1. I need to be to control the GAMA of the images, maybe a scroller on the top of the images or something like it. Optional, give me to diffrent prices for adding this. 1. Be able to report the image, with a FORM. 2. Be able to ZOOM into the images, have like a scroller, like the gamma. If you have a demo/or something like please post a url to it.
