Update
New command and filter afre_portraitmontage. I may add features in the future and conditional checks to make it more robust later. Currently, if you follow the guidelines in the descriptions, you should be fine. Let me know if you have any issues or suggestions. Testing by myself is boring and ineffective.
As usual, wait a hour or so before gmic update and updating your plugin filters.
afre_portraitmontage:
0<=spacing<=10,0<=_colour={[R,G,B]}<=255
Generate portrait montage.
Default values: 'spacing=5' and 'colour=230,255,230'.
Portraits should be centred and have the same dimensions.
