If you're downloading card images for this set from the Topps website, you'll discover that Topps puts the card images in the middle of big square. If you're doing a bunch of these at once, it'll be very tedious to crop them one by one. So I wrote a little script for doing it for the landscape cards. If you have ImageMagick installed, you can run this bash script to perfectly crop all the JPGs in the current directory:
for f in *.jpg; do convert -crop 1770x1264+114+368 $f "crop-"$f; done
If you have any portrait-oriented cards, this won't work, but I suspect you can just swap the width and height numbers easily enough. Anyway, just figured I'd save this script somewhere -- I doubt anyone besides myself will bother to use it but ya never know.
