Scenario
There is a scenario where we need to show the images of the persons from multi people picker column in a gallery. Multi people picker column behaves as a table data type, so we can’t directly assign the value to image control.
Workaround
We have used the nested gallery concept to resolve this issue. Please find below the steps we followed:
List Structure
The approvers column below is a multi people picker column.
Power App
Add a gallery to the screen and bind the SharePoint list to the items property for the gallery.
Add another (child) gallery inside the main (parent) gallery and bind multi people picker column to the items property for the child gallery.
Now add an image under this child gallery and bind the picture property from the people picker column to the image property.
