What about automatically running pngcrush on all uploaded PNGs? In some
cases, this might reduce the image size quite a bit. Do we support SVG
as a format for the icon on the server? An SVG compressed with gzip -9,
with the file extension of .svgz should be loadable by Qt already, and
should be a very significant reduction in file size of the image.
Supporting and encouraging the SVG path is probably something we should
do anyway.

So, require all the icons to be progressive JPEGs instead? ;)
