Here's how to fix the picture in a few easy steps
- Open it up in the GIMP
- Select Layer->Colors->Levels
- In the dialog that appears click the eye-dropper button on the bottom right of the dialog: it should be to the right of two other eye-dropper buttons and an "Auto" button
- With the eye-dropper, click on a part of the image that should be white (one of the T-shirts would be a good candidate). Click on the brightest spot
- As soon as you click the change should be visible
- If you're feeling adventurous, you can click on the middle of the three eye-droppers and select a part of the image that should be grey, but this is a bit harder to get right
- Make sure to click OK in the dialog when you're finished, otherwise your changes will be discarded.
- For last minute tweaking, select Layer->Colors->Brightness-Contrast and muck about with those a bit.
The resulting image should look a lot better, though there may be some speckling (this is why pros use the Curves dialog). Here's my attempt: http://www.bfeeney.uklinux.net/images/group.jpg.
There's a good guide to this stuff at http://arstechnica.com/guides/tweaks/mystery.ars.
