Ah, you want QMimeType::suffixes() instead, since QImage types are essentially 
file extensions.

I had plans a while back to submit a patch to Qt to do implement the 
equivalent of typeForMime and its inverse properly (using the data in the 
QImageFormat plugin metadata), but never got round to finishing it. Hopefully 
I'll have the time and energy to pick that up again at some point.
