After reviewing some comps with @jane, we started on the display of multiple screenshots. An initial rough patch will be up on #19816 soon. We still need to hash out the details of retrieving multiple screenshots, both in get_themes() and from the .org API, and how those images will be added to the extended details div without displaying in no JS, as discussed when first scoping the feature. We also need to take into consideration what happens when the window is resized. Provided that we can get that sorted out tomorrow, it looks like we’re on target for the cycle.
I wrote the Theme Review Team and gave them an update on the anticipated screenshot sizes, which will remain at 300×225 (4:3), constrained by CSS Cascading Style Sheets.. Gandalf functions as the large screenshot 🙂 The screenshots in the list table view will be enlarged to match, as there is more space now that details are hidden by default.
