ASP.NET Image Control

I am building a site with ASP.NET that has a page with an image
control. The ImageURL is set in code by evaluating the value of a
query string that passes a file name for the image control. There is a
folder with over 3,000+ jpg's that we attempt to get the image from -
most are there but some are not - if the image for this particular
search is not present we want to detect that - not by doing a
presearch but by detecting somehow that the Image Control has no
active image - like whateve fires the alternate text event. Can anyone
help with this - how can we detect this and point the ImageURL to a
default jpg when to one we are looking for is not found?

Thank You
