Default map themes are OK, but if I'm creating my own, the picture (tile [0,0,0]) is shown under "General information" in the dialog, but the preview remain black (as well as the final map). Reproducible: Always
I guess it happens because the input image is not in jpg format. I'll commit a fix for that shortly. Please reopen if it doesn't help.

Respect tile format specified in .dgml files during tile creation. M +2 -0 src/lib/MarbleMap.cpp M +1 -0 src/lib/MarbleModel.cpp http://commits.kde.org/marble/858492cd8ea0dea563c0e7927391a7b77484f611
No luck when backporting to KDE/4.10 -- for some reason the <installmap> property seems not to be written there in the created .dgml.
