@sam-pinansky @Rahul-Balaggan Thx

Fixed the code so that it will still run in older versions of e.g. chrome (or the chrome engine usually present in older Android stock browsers), or IE11

@sam-pinansky I just bought a Samsung Galaxy Tab A (mainly to read prepubs from here and books on Bookwalker) and can confirm it has an issue with images loading in the app. Let me know if there's any diagnostics or tests I can do to help.
