Hi Monks, I have written a cgi script that writes a clickable image. I am running the cgi on a windows machine and I am having problems when it comes to displaying the images.

The images used to open up fine but now with the unchanged script(!) they wont open (e.g. the when you click on the image it seems to be looking for it in a different location to where it actually is.

The files are written to http://bioinf/~gb130/cgi-bin/ but clicking on the image looks for the files in C:\Documents and Settings\gb130\Local Settings\Temporary Internet Files\Content.IE5\4949AFKX\21.png and I have no idea why!?

If someone could look at my script to suggest how I can get the image to point to the correct location i would be grateful!
