Comment made at: Clue Comics 012 (paper)If you change the filename extension to .cbr, you can read it normally in cdisplay (or other comic-book reader software, I assume).
Or..... if you want to be able to view the individual .jpgs, first extract the scanfiles as you normally would. Then, load each scan in file-editing software and save it, overwriting the 'original'. You should now be able to view the scan. After doing the whole comic, you can re-save the images in a new .zip file if you prefer.
