Hi. I have no thumbnails in Nautilus for PNG files, although JPEGs show up fine. Is this exclusive to me, or is it a wider problem? (I can’t find much about this problem from googling - one other person I’ve found posted a question about it in an Ubuntu forum in February but nobody answered.)
It’s not just you
There is a bug report on GitHub. If you have any additional details, please add them there:
Thanks. My situation is different from either the original poster or the commenters so I have added a comment. It turns out after further exploration that some of my TIFF and JPEG files produce thumbnails while others don’t.
