I would venture that this is a bug in Netscape, not a bug in PHP and
therefore not PHP's responsibility to fix.
Netscape is reporting to PHP that it accepts zipped content, when it clearly
doesn't accept zipped images.

Subject: [PHP-DEV] Switching zlib.output_compression, bug #16109
> Hello!
>
> There has been a bug report (#16109) about a bug in Netscape 4.79,
> which doesn't display images if Content-Encoding: gzip is used. After
> thinking about a browser detection config flag for zlib.output
