How to Properly Photograph CE Games for use on the site

[twistedsymphony]

I personally take pictures in jpg format in a pretty hefty resolution... then I crop, color correct, downscale them to about 900px on the largest dimension, then add a watermark before uploading.

I'm fine with people sending me the files directly off of the camera un-modified, I'd prefer to do the post-processing cleanup myself. anyway.

though my PC died a few weeks ago and I had some problems reinstalling windows so right now I'm running Linux... because of that I've got no photoshop and have been unable to use my scripts for color correcting/watermarking that I use for the site. I've got a few games worth of pictures that I haven't uploaded because they're waiting to be processed.
