Has you problem with Digital Edition or the eBook Reader?
When i open my book in digital edition and try to read it.
It will lag when ever there is a picture in the book
What device are you using? Have you tried a different book with images? Does this happen on all books that you try?
It could be that the images in the book are resource heavy and your device might not have enough power to display it buttery smooth. Have you tried a different device?
I am using a windows pc.
gtx 980 ti
ram ddr4 32gb
so should be powerfull enoug.
I have tried a note 4 but same problem.
even with the guide book provided by digital Edditon
