your thmbnail doesn't have an extension: do you set the content-type
manually ?

Used the Python Imaging Library (with JPEG decoder) to create set of
thumbnails. For the images with jpeg extension, the error pops up that the
properties can't be retrieved, while for the non-image extensions,
everything displays fine.
Is this a problem with PIL not generating enough header information about
the image, or something else? Size-wise, .thumbnail is 4x smaller, but the
quality is really low. The original JPG displays fine too...
thumbnails resizing:
...
im = Image.open(infile)
im.thumbnail(size)
im.save(outfile, JPEG)
displaying images:
{{

This is the example I used for resizing images: http://stackoverflow.com/questions/273946/how-do-i-resize-an-image-using-pil-and-maintain-its-aspect-ratio, and the one with extension .thumbnail works fine, but jpeg doesn't. I didn't set the content-type manually.

you kinda have to. contenttype is automatically guessed from the extension only. There's no header instrospection.
