<1>if use comes to site with querystring ID then write
out ID.gif</1>
<2>Unique ID will give different images based on
querystring ID</2>
<problem>
some users come with ID that does not have a
corresponding gif image in the directory.
</problem>
<question>
how do i check to make sure there is a corresponding
gif in my images directory so I do NOT get the red x?
</question>

Hi,
The immediate solution that comes to mind is using the
FileSystemObject to attempt to open the file in question, and trap the
error if the file does not exist, perhaps spitting out an error.gif or the
like instead.
Have a search on http://msdn.microsoft.com for FileSystemObject
Cheers,
Ben
