Then, just experiment around with the parameters of the two html files included with the zip. You DO NOT include the .gif extention in the parameters when adding pages. An image with a higher color depth than 2 will not color clearly, and the trace function is likely not to work at all. You can replace the rainbow graphic by replacing the pal.jpg file with your own graphic. Select the pallete box you want to replace the color in.
Color just colors solid.
OWL.gif should be passed as OWL, not OWL.gif. If your image shows up on the applet, but will not color, then you need to check and be sure that the background on your .gif file is transparent. If the tracing feature does not work on your image, or the image doesn't color solid, then you need to lower the color depth of your image to two colors. Many have suggested making a save function on the applet to save a browsers colored picture. Due to javas security features this is only possible through the combined use of CGI scripting and java.
