[Qgis-user] Show multiple photos attached to one feature

Sat Oct 17 11:20:28 PDT 2020

Hi,

Did you simply try a drag'n'drop custom form ? It's not a well documented
feature but it's really easy to use. In the layer properties, go to
[image: image.png]
And for all the pictures fields, choose attachment as widget type and the
following options (click on the left panel to choose the field, the middle
panel is to arrange the fields)
[image: image.png]
Now, your form is able to display correctly any numbers of well
dimensioned pictures. Use the middle panel to group them, create tabs or
containers (a bit tedious, but it works !)

Regard,

djes

It passes the contents of the "filename" field for the feature as a command line parameter. (essentially runs the command: /home/baw/qgis/open_images P1010005.JPG P1020700.JPG

It contains all the fields including the photo field but this contains only one photograph in this format- DCIM/trees_20201010165100197.jpg but not the rest.  How can I have the rest of the photographs listed here too?
