Ok, didn't think of that, these are mostly using the QImage LoadScale version?

I'm thinking of modifying the LoadScale function to also deal with scaling the 
images to it's final size if needed, so they can be cached as well.

Or QPixmapCache, but I figured most of the images was in memory all the time. 
The ThemedMenu pixmap at least has them loaded all the time, so for this to 
work, I would have to ignore them.
