File's image well displays PNG icon not actual PNG I would like to replace the standard icon for an Automator application that I created with a PNG.  Unfortunately, the resulting icon is the generic PNG icon, not the actual PNG image.

Steps:


downloaded the desired image (512 x 512)
verified that the image had a transparent background
Opened the file's inspector window (⌘+I):





Dragged the PNG to the image well:




The final result:



Is there a way to get the actual icon to be used?
Copy paste the .png image onto the icon shown in the Inspector.


Open the .png with Preview
Select all with CMD+A
Copy with CMD+C
Select the application of which you want to change the icon.
Press CMD+I to open the Inspector
Click on the icon and paste the copied image using CMD+V


I have no clue why that works differently compared to dragging and dropping the image.
