We have moved the forum to https://forum.ngsolve.org. This is an archived version of the topics until 05/05/23. All the topics were moved to the new forum and conversations can be continued there. This forum is just kept as legacy to not invalidate old links. If you want to continue a conversation just look for the topic in the new forum.
Instructions are here:

But maybe we can pack the jpeg support into the next installer, I'll keep you updated. You could convert the ppm to jpg as well...
