I followed your instruction and that fixed the problem for my  
original images.

Thanks.

I found some more work friendly non-JFIF/Exif JPEG images here:

Firefox and Emacs 22 fail to display these images, but Emacs trunk  
displays them (is this the case with the images in the original  
report?).

The difference between Emacs 22 and trunk seems to be in the function  
image-type. In Emacs 22, if the image headers do not determine the  
type, we convert the file extension to a symbol and use that. This  
means .jpg files are given a type of 'jpg, which is not the correct  
image-type for jpeg images.

The trunk has been changed to use image-type-from-file-name instead,  
which correctly returns 'jpeg for that image.

I have backported that change to emacs-22.
