The rule in software engineering is: Its better 1 person does the hard work once and everyone benefits from it; Rather than everyone having to do a hack.
btw in this case its also less work to just add a standardized size set of jpgs to a folder and have it show up as a theme.
I dont know why you guys are going out of the way to make this complex?
Still disagree with you guys though--this is not the way to do it. Isnt it easier to just drop a bunch of svg/png files into a folder on the server; and every folder is a theme?
This way everyone already has access, without installing plugins, it doesnt need external hosting, etc
Thanks, I just noticed that some pieces render slowly.
Benevolent dictator >> @thibault doesn't add user defined style to lichess. Because the number of them are huge. There are more than thousand of them. So that addon is a good solution.
