Description:
------------
if php.ini has:
    output_handler = ob_gzhandler
dynamically generated JPGs are output with gzip (Content-Encoding: gzip).

if php.ini has (instead):
    zlib.output_compression = on
dynamically generated JPGs are output without gzip.

In both cases the HTTP request includes "Accept-Encoding: gzip".

It does seem stupid to attempt to compress a compressed image file, but I can't find any documentation that explains which way is the "right" way to do it, or how to override the default behavior.

If nothing else, this would at least be a documentation bug.

I can confirm the behavior but could not find any place in the sources which explains it.
