I’ve requested this before but I’m bringing it up again as my current project could work with it.
On Tsumego Dragon there is a feature to unlock board and stone skins. On this window you can copy the url link to the image. My hope is that the users can copy these links and use them on OGS in their own games.
What users can currently do.
The goal
I love it <3333
Maybe same “custom url” than with board backgrounds?
Yes. Image URL for each stone just like the Goban has already.
This looks pretty feasible.
There is a catch though: whatever image you provide is going to get various things overlaid on it:
… etc.
Is that going to put you off?
Initial take on this here:
FYI the feedback on my initial attempt is along the lines of “nice looking thing, but more work to be done to make it suitable for release”.
So I’ll do that, when I have a chance.
I’ve found it more entertaining than I expected, plonking down cats on the board 
Oh wow … I’m not usually into that kind of stuff (like, TOTALLY not), but your images are lovely, @GreenAsJade 
(The white ones could use a little translucency though, I think, if possible, to make them a little less rich in contrast.)
Me too 
All you have to do is make the image you like available on the web, and point your OGS client to it, and bingo you have it 
That cat face is just a random cat that I pointed at, on pixabay

But why oh why are both colours cats??? It would be much more suitable to have the black as mice!
Like this ? ^^
Yep, just work on the relative sizes! 
These should be transparent. ^^
(Edit, woops, wrong images the first time, reuploaded them)
but black cats are so iconic! 
Next up: animated GIFs as stone images? 
Never please. (Animation)
Sadly, animated gifs are not supported. I actually would have liked spinning sun on my board
(At least, for a moment of entertainment )
Fascinatingly, plain images posted here in the forum are supported … I’d thought that you might have to host them somewhere else, but posting them here is sufficient, the forum image URL works - obvious in retrospect, but certainly “a nice easy thing”.
I’m so happy this is being looked into!!
The only thing holding it up is that the extra option has tipped the design of the theme picker “over the edge” and it’s needing a bit of re-do 
The actual function works (but only on my machine 
) !
Since nobody pointed out the obvious answer:
Anyway, this is great, can’t wait to see it in action
