It works, but Interchange is not the fastest method for serving files.
You could pretty easily make IC the 404 handler for images if you use
Apache, and have it pull the image out and place it on the file system
If you make "AcceptRedirect Yes" in interchange.cfg, IC will take
Apache's redirects when you make it the handler for 404. You could
intercept the request in Autoload, and:
* determine whether the request asks for an image/* MIME type
* pull the image out of the database and write it to disk
* deliver it with $Tag->deliver()
Apache makes it relatively easy as I believe you get a PATH_TRANSLATED
variable that tells you where the file should have been.

No, that is an interesting application. It would certainly make it
easier to transport a catalog, as finding the image path and
copying the images is one of the hardest part of moving the
