i have got a bit success in going through the interactive html page. i have used exampe1-9 of the tutorial, which is working fine, but as soon as i change the map file to my own data, then i get the full image only once i.e. at the time of first load. as soon as i click the image at any location, i get a blank image, and that is what is saved in the tmp directory, a blank image.
why my new image is not being saved and displayed, can anyone please help. thanks.
