For some reason most of our images have been created with a depth of 16 bits per channel: > tlclient_192.png: PNG image data, 192 x 192, 16-bit/color RGBA, non-interlaced The reason is probably because they are generated from a SVG and include gradients. ImageMagick then likely concludes it cannot reduce the depth without losing some information. But this is overkill for us as these images will not be used in places where such precision is needed. We can save quite a bit of space by reducing things to the more standard 8 bits per channel. In the case of tlclient_192.png the difference is 59722 bytes vs 14886 bytes.
Tester should check that images still look okay: - tlclient icon on Linux - webaccess icon - tlwebadm icon - big logo in tlwebadm - logo in tl-xstartup-feedback - logo in profile selector - logo in rdesktop launcher
