An unfortunate behavior of IE7 is that it assigns content type image/pjpeg (progressive jpeg) to all jpeg images it uploads. We find that Prince does not render these when we then serve them up as image/pjpeg, even when the image is really just plain jpeg.

'm close to just replacing all those incoming types with image/jpeg, but that might fail for a real pjpeg image, and I don't have time to implement sniffing of the file info to be sure.

Any chance we can get support for that type?

Sure, we'll add support for image/pjpeg in the next maintenance release.

Terrific, that's great to hear. It will save us work and keep our own code cleaner. Thanks, Mike.

The new maintenance release is out and includes support for the image/pjpeg MIME type.
