[Qgis-user] ideas/examples of atlas/report with multiple pictures for each object?

[Stefan Giese (WhereGroup)]

Hi,

I would use an Atlas - better then report, since reports haven't been 
further developed - and then use 3 pages. You can add pages clicking in 
the menu: Layout -> add pages. Then you go to page properties for the 
second page. there is a checkbox "exclude page from export" where you 
can use data defined override to check if the first photo on this page - 
photo number 3 for example does exists. You can use the function:

not file_exists(@project_folder  || '/photos/' || "object_id" || '/basename_' || "picture_id" || '.jpg').

If the photo does not exists, the page will not be exported, do the same 
with the third page...

Best regards
Stefan
