Max pixel size, please? P-man, you don't want to resize so many pictures, do you?
640x480, 800x600 or 1024x768 ?
Also, multiple images (for example front and rear) in one picture is permitted, right?
<Tip for new members>
* Web camera is no go. Arrange to borrow a digicam or SLR from your friends before the contest.
* Good lighting will greatly improve the photo.
* Don't try to fill the view finder with a model to take a close up photo, or the image might turn out blurry. Try to focus first, then crop the image with a photo editing software.
