SLES seems to be using png

Not a good reason IMO. What's the size difference?

That speaks very much for jpg (wasn't png supposed to compress better?)

The benefit of png is that it's lossless, jpg doesn't compress better unless it loses detail

with optipng -o7 (slowest) total 5.8M removes about 100-200K from each file. Adds two-three minutes on build time.

The main benefit is running SLE Micro cockpit on LeapMicro without rebuilding and need for a separate update channel just for cockpit :-)

I don't see the compat symlink creation in the diff. In any case, it seems like the wrong approach to me

Let me fix that. Sorry I originally wanted to test this all out on 16.0 / Micro 6.0 first
