First, I think you should list the images in a column and not in a row.
Second, the images are indeed scaled to 640 pixels, but sometimes it's the height and sometimes it's the width. Since you claim that you have set the "weight" to 640 pixels it's extra confusing what you have intended to do.
The width of a background isn't extremely important, since it will simply scroll if it exceeds the screen resolution. The height is - unless the background should be vertically scrollable - more important to have constant.
If you settle for 640x400, at least make sure the height stays 400 pixels throughout your images.
And I think you should save the salesman-talk for the GiP board; "cool-ass facts" don't really have a place in an artistic analysis.
As for the photographs; I guess some of them are visually intriguing, although I'm not sure the editing you've done has improved them much. The problem with using photographs instead of handpainted backgrounds is that the demands are much higher. Handpainted backgrounds must be good to work; photos must be excellent, or the whole thing will fall flat.
