I have an epub which gives no error when validted by epubcheck.
But I wanted to decrease the epub size, so I compressed the jpeg images in Calibre with lossy compression. After that epubcheck gives an error message for every jpeg file: "Corrupted image file encountered."

See the attached image as an example for "corrupted image file".

@bitcoin333 Reproduced this with EPUBCheck 4.0.3 on a MacPowerBook running 10.12.6. Interestingly, while developing the EPUB, there were a few minor errors (incorrect OPF, etc.). When those were eliminated, EPUBCheck returned the error

ERROR(PKG-021): ./Tiny-Corrupt-Image.epub/OPS/images/corrupted.jpg(-1,-1): Corrupted image file encountered.

But the file is NOT corrupted according to Preview and Photoshop

Attached is the EPUB file (with zip extension).
