ArcGIS Online Popups with Multiple Images

Question

I have a polygon layer that I want to add popups to. Some of the polygons have two records and images associated and some have three. The ones with three are working fine but I want only the two images to be displayed when there are only two but I am getting a place marker being displayed.

I have defined a custom expression to test if the attribute is null but not sure how to stop the place marker being displayed and only the two images for that polygon..

That is what I have done, the arcade expression is used in the Attribute expression and then make use of the attribute expression in Custom attribute display.

Thanks @ManishPatel , yes that seems like a very easy approach but would be great to know how the custom expressions can be utilised.

The custom expression I am using just tests for a blank attribute

Text(IIf(IsEmpty($feature.Photo3), "", $feature.Photo3));
