helpful to the developers working on the module.

> Are you saying that you requested an image and it gave you this error 
message? That's good to know. It means that it was parsing that image as an 
html doc! I believe we choose which files to rewrite based on MIME type 
reported by Apache, do you think there would be any reason that this would have 
been reported as text/html or anything like that?

Thanks for your explanation of the error messages. The images are
generated in PHP and are loaded using a url ending in .php, but I set
the content-type HTTP header to image/png, so it shouldn't be an
issue.
Here are the response headers for one of the images that resulted in
the above error:
