I'm looking for the ability to simply drag a photo (such as png) onto a layout in Pro from File Explorer or another tool I use called Everything search (which does allow for drag and drop of things like shapefiles). Currently though I get the ":prohibited:" cursor from either source.
I also tried dragging the .png from the catalog pane and that didn't work either, nor did copy > paste from any source. It seems the only way is to manually go Insert > Graphics and Text > Picture and re-navigate to your graphic.
Drag-and-drop would provide intuitive functionality consistent with most other graphic design programs.
