--- Comment #4 from tagwer...@innerjoin.org --- https://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html Which talks about attributes in the PNG file: a couple being required: Thumb::URI Thumb::MTime plus some additional, including Thumb::Size If I poke around in my thumbnail PNG's, I see that these are being used. They would be enough to catch the issue I was having. The spec also leaves open the option of further 'X-' prefixed attributes. -- You are receiving this mail because: You are watching all bug changes.
