Thanx for answering. Indeed there is something about adding photos, but
actually this version of the doc is somehow not showing up in google
searches:

Furthermore, I did not have the problem of having to construct a path to
the image. The full path is already in the data (from the nice toolbox
function for geotagged images). The report just did't eat the path.
After dozend and dozends of attemps, QGIS somehow seemed to give up on
refusing them, and now miraculously is accepting the path.

The problem, that all images where repeatedly showing in all section got
solved too. In the level up for the subplots, I had to use the field
unique for each subplot and not that for the plot, as I wrongly assumed.
Having it set wrongly didn't influence the correct print of the plots
and then their subplots, but had influence on the follwing photos. Pfuh,
the logic behind, how the report "knows "what to print in lower levels
is actually not really obvious, It seems to figure this out on its own.

So, seems I get it working.

Major flaws:
There is only the possibility to select an existing field for a layer in
report groups. So the data has to be prepared for each and every
possible usage beforehand. Having the possibilty to use expressions here
would be phantastic. So now, when you find out that you had not the
right variables for your job in the data, you have to stop working on
the report and fumble the stuff into the attributes. I worked around
this problem by setting up a nice model to prepare my data, but not
everyone has the knowledge to do so.

Found no way to add sections within the "tree" or to move anything. Once
you laid out a design and forgot a title page or mid-sections, you seem
to have to restart from scratch. No way to manipulate it later.

Found no way so far to add page numbers.

All in all. Spent 2 days now on this 30 page report and I hope I will
remember next time how to glue things together.
This could be a really powerful tool for lazy people having to do boring
reports frequently. So far, no time was gained, and I had to use extra
doses of alcohol not to give up.;)
Hopefully developers will give it a little more love some day to make it
a bit smoother, then it will really rock!
