That won't work well --- it's hard to generateimages from JavaScript. (Although my officemate did it by generating a16x16 frameset and changing the background colors of the frames.)Anyway, if you can specify the inputs to the image generation, you cansay something like <img src="img.cgi?data=1+3+4+17" /> and generate theimage from a CGI script. Just print "Content-Type: image/png\r\n\r\n" + pngdata;It's sort of a hassle that you can't do this from the initial script.-- <kragen at pobox.com> Kragen Sitaker <http://www.pobox.com/~kragen/>Perilous to all of us are the devices of an art deeper than we possessourselves. -- Gandalf the White [J.R.R.
