In AceConfig-3.0 Options you can set an image to be displayed instead of an execute button.

But I don't understand how you are supposed to pass the imageCoords, as it says in the manual:

• image (string|function) - path to image texture, if this is a function it can optionally return the width and height of the image as the 2nd and 3rd value, these will be used instead of imageWidth and imageHeight.
  • imageCoords (table|methodname|function) - arguments to pass to SetTexCoord, e.g. {0.1,0.9,0.1,0.9}.
  • imageWidth (number) - Width of the displayed image
  • imageHeight (number) - Height of the displayed image

The 1st return value is the image string, the 2nd and 3rd is are width and height. But what about the imageCoords table??

image = function()
    -- What do I do with this?
    local myCoords = {0.4, 0.6, 0.4, 0.6}
                                  
    return "Interface\\Transmogrify\\Transmogrify", "20", "20"
  end,
