Thanks

[leotaku]

A similar problem, albeit related to PNG decoding instead of JPEG appears in #6. As I've written there, there's very little I can do to fix issues like this. Images that are "broken", as in, their encoding is not correct according to the standard, can often still be displayed. However, it is also correct behavior for decoder implementations to reject these images. As I use the Go standard library for decoding images, I can not fix this issue here.

As mentioned in the referenced issue, you could either exclude the offending chapter, or report the issue to the scantlation group, who could then fix their image.

Understood, thank you very much.
