Adding costumes problem

I'm adding costumes to Snap fork, but it does not show any costumes I added. Can someone help me with this. Feel free to move this if this is in the wrong topic.

Are you having a problem with uploading new costumes to the library or just uploading an image as a single costume in the editor?

uploading an image as a single costume

You have to drag the image (from your files) into the costume editor.

It should work just like normal Snap!.

I mean I uploaded files here, and it's not showing the costumes

That's not the editor; that is the costume library. I'm not sure about that...

I also added the costumes in the sw.js file, but it's not showing them

It's not showing them in Snap! Fork or in the GitHub folder?

in snap fork

oh, ok
