Can we control the image size in the Report?
Yes you can do that with the format rule.
@Aleksi_Alkio Can you please tell me how it can be done?
If you add a format rule for that image column, you have the option in that format rule to choose the option Workflow templates/Image size.
One other way that works a bit is to put the pictures in cells within a table.
It doesn’t always behave correctly, but it gives you some control.
