Horizontal Scrolling

Fantastic plug-in, works amazingly.

I do however have an issue with images that load in a horizontally scrolling block.

I have a section that allows horizontal scrolling. The initial position of some thumbnails are outside the viewport (to the right). Unfortunately these images don’t lazy load until they’re within the viewport and the vertical scroll is adjusted (and therefore recalculated).

Is there a way to implement a Horizontal Image Load Threshold for thumbnails in this situation?
