JPEG / PNG Image Resizer
Parameters (passed via URL):
img = path / url of jpeg or png image file
percent = if this is defined, image is resized by it's
value in percent (i.e. 50 to divide by 50 percent)
w = image width
h = image height
constrain = if this is parameter is passed and w and h are set
to a size value then the size of the resulting image
is constrained by whichever dimension is smaller
Requires the PHP GD Extension
Outputs the resulting image in JPEG Format
