At the moment, i am plying with the GD functions using Jpegs and the Image
Resample function.
I was wondering if there is a way to add a second image over an existing
image.

I am working on a shopping cart system with thumbnail images and I want to
do one of the following depending on which looks better:

Create a "SOLD OUT" Image over the existing image
Turn the image to a Black and White Picture
Turn the image Black and White and cover the image with a sold out
image/text

Any help or suggestios would be grateful
