I assume you have this many controls displayed because you can scroll the
page (card).  I think with a bit of work you might be able to build this
more efficiently by grouping the controls needed for a single photo into a
master group, and then populating the card with enough master groups to be
able scroll one ore two groups out of view. As one group is scrolled out of
view at the top or bottom of the screen, the off-screen group is then
repositioned at the other end of the screen and populated with data from the
next thumbnail before it comes on-screen, and so on.

I've built something similar to this where a horizontal line images can be
"infinitely" scrolled left and right.  It uses the minimum number controls
needed to display content on screen at once, plus two, allowing for
scrolling in either direction.  As one image is scrolled out of view on the
left, it eventually reappears into view on the right.

It's bit difficult to describe but this arrangement may be more efficient
than a situation where the majority of data is sitting off-screen.
