@hexedpress Hey. I created a solorpg community on lemm.ee, but I’m having trouble uploading a banner for it. Mine is the same dimensions (1200x514) and same format (.webp) as yours on @osr, but still I get a JSON error message when I try to upload it. Do you remember if you had to do some special trickery to get it to work?
Make sure the size is under 100kb. Run it through https://squoosh.app/ and drag the slider down to compress it below the threshold. Save the compressed image and try it.
@HexedPress Ah, good point, thanks. I forgot to consider the file size.
