Hi Harrissou,
thanx for the hint. I already saw the checkbox, but had no idea what to do
with it.
My problem now is, that I have really no idea what to put in the "case
when"
Maybe something like
'/mypath/'|| @atlas_pagename ||'_1.jpeg' IS NULL or so?
I do not know what is expected to be returned that this option will
trigger. There seems not to be a boolean type or so. The documentation
does not tell what to do there.
Still confused, but there might be a solution...

Hi,
what about using the data-defined option near the "Exclude items from
export" in the items properties --> Rendering (with a case when
>expression)?

Hi,
I set up a neat atlas for displaying a row of 50 sample plots. On a
second page, I want to show 2 pictures taken of these plots
>>automatically with an expression including the path ||
@atlas_pagenumber || '_1.jpeg' or '_2.jpeg' to display up to two photos
>>named e.g. 1_1.jpeg, 1_2.jpeg.
This works really great! The problem is, that for some plots, we do not
and have any picture or only one. In composer, these >>missing images
are marked with a big red cross.
Unfortunately, these red crosses are also exported, which looks quite
shitty.
Is there any clever way of forcing QGIS not to export these place
holders but just not to print anything at this place?
The only (boring) idea I came up with till now, was to create empty
white images and name them accordingly to avoid the red >>crosses.
Thanx
Bernd
