Can't create a collage with Photos
All of my photos are stored in the mac Photos library which comes with my mac.
I want to make collages and I have downloaded PhotoScape X to do this.
However, I cannot access my Photo library. There are a very limited number of extensions available when I try to "share" the library and none of them appear to include any third party software which can let me make a collage. On google, it appears the only extensions are to edit the photos and not to make a collage.
Does anyone know if it is possible to make a collage without re-saving all of my photos outside of Photos for mac? I am happy to use any other apps to do this although it seems they need the right extension to actually access my photos without me duplicating them.
