I think this is just a packaging bug in that the qt jpeg drivers
probably arent packaged properly / at all. Marco Pasetti would be the
guy to go to on this.

>> Hi QGIS Windows users,
>> I have a strange problem that my QGIS Windows build (Metis) doesn't
>> support the display of image/jpeg with WMS. It works fine in Linux,
>> but not in Windows. I only get image/png as a choice, although the
>> GetCapabilities output of the WMS shows support for gif/jpeg/png/tiff.
>> Is this due to a bug in QT for Windows? I replicated the behavior on

> I was told that at least QGIS 0.10.0 (IO) had that problem, that the
> windows build was built without JPEG-support. It seems that this is
> also the case for 0.11.0 (Metis).
>> On the same issue, we discovered that some WMS (e.g. UMN Mapserver)
>> offers two version of PNG:
>> <Format>image/png; mode=24bit</Format>
>> QGIS only picks up the first variant, but in my case I want the
>> second one - jpeg is prefered, but png/24bit would be the second
>> choice. I am serving orthoimages in this case, where we want 24bit
>> color depth.
>> The second issue affects all versions of QGIS, while the first issue
>> only appears on Windows - works fine in Linux/MacOSX.
>> Thanks for any feedback on this issue.
> I leave this topic for others, since I don't know anything about that.
