Ok, I have an image and a map over it, making an image map of course. The image is divided up into regions that are different colors. But the colors change. So what I want to do instead of updating the graphic every time it changes, is to make a table and list all the different regions of my image in it, as well as their current color. Then I want PHP to retreive that information and apply it to my image.
So, for instance, I have a square. Right now the top of it is green, and the bottom is red. So you leave and come back the next day, now it is supposed to be blue and yellow. How do I use PHP to modify my image without actually uploading a new one. I can have a white background, and then declare the coordinates of the regions and somehow do that. Or how do I do it?
