GD Library Helpers
LIGHT SOURCE Giving your creations a light source makes them have more demension. These light spots can be accomplished by overlaying your GD graphic over a gradient. The gradient should be the same size as your image. From my experiments these gradients should neither be black or white but shades of grey in between. These gradients both use 220,220,220, as the lightest color. 
 Here are the graphics before and after being composited on the light source. 
 Here's a zip of both gradients to play with. Remember it is important that your drawn images and all outputs be True Color....
