Yes read, Thumbnailing, in IM examples... http://www.imagemagick.org/Usage/thumbnails
to process them all at once use mogrify (see http://www.imagemagick.org/Usage/basics/#mogrify) but be very careful you understand how to use it. Try it on some test images until you get the hang of it.
If all your images are different sizes, you cannot make them all 80x80 as IM will keep the aspect ratio of your original. Thus you will need to crop them or pad them after you scale them.
See -thumbnail or -resize and the use of the ^ option. (If on Windows ^^, as ^ is an escape. See http://www.imagemagick.org/Usage/api/#windows)
