So I was converting some manga for use on my Sony Reader when I discovered an issue. Some of my files were not being converted into CBZ formats upon adding to calibre and would not convert into LRF. I looked into it and thought at first it was an issue with PNG files but have since discovered it is not. What is happening is that I have a zip file with both JPG images and PNG images in it. This causes calibre to to give an error resulting in an unconvertible file. One solution I found was to convert the files into one type of image (i.e. all png or or jpg), create a new archive, and it will then convert properly. Not sure if this has already been mentioned but I figured if it hasn't, some others could possibly benefit. Maybe a future version will be able to correct this so multi-format archived files can be converted properly.
Code:
ValueError:Could no find an ebook inside the archive
