Does this mean that your imagemap HTML is static and you just dynamically create the image?

In my case, I am wanting to dynamically create the both the imagemap and the image. I think I am just going to to try calling the dynamicimage.aspx file twice and get it to return either the image or the imagemap depending on a parameter. I don't think it will add too much overhead.

Thanks for your help,
Phil

Ah yes .. perhaps it is what you already have... DOHH

I my case I have only two files: 1) The imagemap HTML Code file that calls
2) the dynamicimage.aspx. This way it is automatically 'returned' to the
HTML code after the image is processed.

Would this way work for you?
.. or do you need the actual text stream of HTML code as well?
