[Qgis-user] Report Layout strange behaviour with photos

[Andreas Neumann]

Hi Bernd, 

The report functionality definitely needs some love. There is a great
base now, but it needs to improve. 

Would you volunteer to collect missing things regarding reports in a QEP
and then help organize a crowd-funding? Even if you can't fund this
yourself, it would help a lot to come up with a sound proposal /
specification, that some interested developer can submit a quote and we
can look around for funders. 

There are quite a few successful examples in the past where someone who
missed a functionality in QGIS but couln't finance it came up with a
sound proposal and then we could find a developer and funders based on
that initiative. 

Or you could organize this as a joint effort - e.g. through the german
QGIS user group. 

Greetings, 

Andreas
