I've developed a library to create epub files from collections of images (source code at https://github.com/Aftnet/CPubLib if anyone's interested).

The files generated are epub3 compliant (validator passes them) and so far work as they should on
- Edge on Windows 10
- iOS and macOS's Books app
- Lithium on Android
- Kobo app on Android

Kobo devices however ignore some metadata: cover and, more importantly, chapters index.

Is this a known issue with Kobo ereaders? Any chance of getting them to fix it?

If anyone wants to test for themselves, here (https://drive.google.com/open?id=12e...Fgg75qQuRBe1ZI) is a sample. It has a cover and a chapter for each page.

P.S. For those asking why bother making this vs just using CBZ/CBR, those formats are not supported by native (as in, built into the OS) apps on any platform and they do not have metadata, making organization a pain on Kobo devices.
