Description: User wants to convert an image in PNG, JPEG, or other format to GD2 format for use in the statusmap CGI.

Solution: First, get your image in PNG format. Then convert the PNG image to GD2 format using the pngtogd2 utility. Use a chunk size of 0 during  the conversion to create an uncompressed GD2 image (compressed GD2 images slow down generation of the statusmap CGI image).

More information on the GD2 file format can be found at http://www.boutell.com/gd/.
