The Bard Storyteller text reader (created by Alan W Black) has been recently update to version 0.7.
It now support the ePub file format and has initial support for images.
I have tried it with a file in the Czech language and
it works nicely. Only images they are not shown (I used the Czech openMagazin file from here: http://www.openmagazin.cz). I’m sorry for the gray background, it is not default but I like it better than the white one.
