I have several image files that were originally
.png, but due to my own needs I changed their name to some custom extension
Thankfully, I can still preview the images using the spacebar, so that's great. However, their thumbnail is blank:
Is it possible to tell Finder to render the image for files with extension
.xyz? Note that the file contents are identical to that of a
.png file - it's just the extension which is different for my own needs.
I am running macOS High Sierra 10.13.2.
