Can this be done in Sparkle?

See this Site: The image changes at certain scrollpositions while the textboxes flow with the scroll – can this be done in Sparkle and if so: how?

Thanks for your help.

Wow, this would be a challenge @abra100pro.
I wonder if you would use (Animate While Scrolling) vertical motion and opacity on every image block to give that image replacing image effect?..

Thanks, Hendrik, I definitely give it a try.
