Imgbot broke JPEG

[MichaIng]

Just faced: https://github.com/MichaIng/DietPi-Docs/pull/794/files

See the Dropbear logo at the bottom, which has its bottom content removed.

Hello, we will review this issue, but it would help if we would have a larger sample of images that are breaking to identify patterns.

For now you can use our ignoredFiles option to exclude the image with the issue from optimization as mention here: https://imgbot.net/docs/#configuration .

For me it is as well the first JPEG I see breaking, so I have no other example. Out of interest, I saved the file again with GIMP, removing some metadata. If this works, it might give an indication.

Would be helpful if you could link the PR. Probably we find a pattern in the JPEG which is falsely "optimised" by the library/tool ImgBot uses.

Of course, GrigoreMihai asked for further examples. I have only one, so if you have another one, that might help. An "I have the same issue" comment doesn't help here, but the JPEGs themselves are needed to investigate why this happens 🙂.
