tkjpeg man page
tkjpeg — simple JPEG viewer using perl/Tk
Very simplistic image viewer that loads JPEG image, (well actually anything for which Photo has a handler) and puts it into a Label for display.
It tries to find a fullcolour visual to use if display is deeper than 8-bit. (On 8-bit it uses a 4/4/4 palette.)
