[Qgis-user] Report Layout strange behaviour with photos

Tue Sep 15 02:17:05 PDT 2020

Hi Andreas,

hope I did not sound too negative. For sure I would like to help in some
way. I give money in nearly every crowdfunding project, though I even
don't need most functionalities there.
Around the report function, there is quite a sounding silence in the
lists and the web, so I assume that few people use it, or feel too
stupid to ask cause they don't get it to work properly.

What I already tried, was to collect issues on github for the Report 
But already there the problems begin: There is not a label for it (only
a general "Print Layout") and report is a very common word)
This may be intended as the reporting seems to be the younger brother of
the Atlas, but makes it not easier ;)

Before I would be able to create a QEP, I would need someone to explain
me the parts in Report that I maybe simply do not understand.

So, count me in (at least a bit ;) )

Bernd
