We have thousands of JPEG and GIF images that are displayed in internal web apps. Many of these image files, however, does not have a file extension. On Windows 2000 (IIS 5.0) this was no problem - the image file was sent to the browser and the browser recognized and displayed all images correctly.
But on IIS 6.0, I find that files without extension (no associated mime type) are not allowed, so I get 404 - Not found for all these images. If I add .jpg to the file name I can see the image, so it's not a matter of rights.
Does anyone know how to instruct IIS 6.0 to also allow files without extension?
