Finder window background colour or image for USB Drive I would like to know how to add an image (if that's not possible then a colour) to the Finder window of my USB stick - just the stick not every window.
I have seen it on various .DMG installers (the ones which require the app to be moved into the applications folder often have an image with an arrow and a text telling the user to drag and drop) and now wonder how this is done for the window of a USB drive.

I have an application which runs straight from the stick itself without wanting to move it to the apps directory of the Mac. Every time I click on the USB drive I would like to see a custom image background (much like on those DMGs).

Search results returned old and obsolete ways or partial answers no longer supported by macOS Sierra.
Only works in icon view &amp; as far as I'm aware only on HFS drives.
I quickly tested with a FAT32 drive which appeared to work, but didn't survive eject/insert]
