Removing empty space around the central artwork, centering it and downscaling it is trivial with code.
>use an online downscaler, since no software can do it as smoothly.This is a lie. It's called Cubic interpolation and many image editing softwares support it, as well as a script.
Processing all images at once for one sheet of these would take less than 10 seconds.
You would provide data on each entry such as name, types and artist name, i suppose its not a step up from how youre already tagging maps.
The script would also have a folder of respective images for type icons, and would draw squares with text info, type icons and the processed artwork into a large image pretty much instantly.
Look into python and the Pillow framework for image manipulation.
