Do you also have image upload issues sometimes? I have posted a screenshot of how it looks when it fails. It is a known bug -> https://github.com/LemmyNet/lemmy-ui/issues/1489
Do you maybe know how to get around it, and still be able to upload the image?
Interesting, I did not know about pict-rs. Thank you, I will just try again, maybe with a downsized version of the picture.
