How to install the retro image set into an existing server:

1. Apply image_info.patch and merge the folders of images into an existing arch directory.
2. Ensure that there is a link to arch (or your arch folder is directly stored) in the lib folder.
3. Run `make` and `make install` with appropriate permissions at the top level of the server.
       This will copy the compiled image file to the installed data directory.


Why this exists:
I was on the Crossfire Discord/IRC bridged channel (it was late August 2020, I think), and we got on a discussion of how using the old images on a modern server would work.
We concluded that to use them, you'd have to scale up the old 24x24 images to 32x32; we weren't sure if JXClient supported arbitrary tile sizes. but were certain that the GTK2 client did not.
Having seen the end result of scaling the images (there were some left over in trunk; I usually tried to replace them because the upscaling makes them look hideous), I set out to make the GTK2 client support arbitrary tile sizes, and produced this repository as I scoured the 0.9x.y versions of the archetypes for the old-school images. I converted them to PNG, figured out which images I was still missing, and downscaled trunk images (classic where possible, else base) to fill those gaps.
Now I'm going back through and creating new art (or, when possible, recoloring the existing art) in the general style of the 0.9x.y artwork to make a more cohesive image set out of this.
