It will be great if lazy loading for images via js could be implemented for Veronika theme and other themes, because google page speed do not like hiding css styles , and drops down speed loading dramatically for mobile view with warning:

Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive.

You can activate lazy load for images in theme settings.

ok...hm...what name of this check box or option....?

I will have to check

seems with MEDIA settings

Force aspect
Force image aspect. No white background will be added to keep the size. = CHECKED

$("img.lazy").lazyload();return the error
TypeError: $(...).lazyload is not a function
With UNCHECKED  option
$("img.lazy").lazyload();is working fine

But in second case when lazyload is working fine few problems comes up:
1.if upload portrait image , taken from mobile phone, during posting , this image rotates to landscape (
2.if upload portrait image from PC during posting, it becomes aligned to left in gallery view, rest of right side become white (

seems it it is osclass bug, not sure
can you reproduce on your side ?



thanks

@Ivanko
Yes it must be checked.
