My cam takes (due to my settings) always 2 images. One in raw and the other in jpg format. When I check the images on first sight I tend to delete the raw images when they are not better or if the jpg has sufficient quality. so I'd like to see which one is which when in fullscreen mode.
Type mime of image can be displayed over thumbnail using right option in Album View settings. This is not enough for you ? Gilles Caulier
