One of the things I have to admit I like about Windows is its ability
to display thumbnails of all the images in a folder. Now you can do the
same thing under DOS, at least for these file formats: BMP, GIF, LBM,
IFF and PCX. Meticulously commented source code is provided so you can
add the formats you want. Download THUMBS.ZIP (34k, 26-Jul-2011).
