Are we supposed to format images for them to show up as Home Page Tiles?

How do I control Tile images?
I want this simple image, green chevrons, to be turned into a thumbnail for the Home Page tiles.

However, when I view the page all I get is a green box:

I'm controlling my tiles from the TOC and under My Frameless output preset I've selected:
Layout > Use template home page
and under Show Thumbnails for images, I've had no luck when selecting Create Thumbnails for Images OR Style Existing Images as Thumbnails.
Any thoughts?
