If anyone is interested, here's an alternate version that I'm not submitting because it takes up too much space on mobile:
<includeonly><div class="mw-collapsible">
<b style="font-size:120%">List with thumbnail images</b>

<div class="mw-collapsible-content" style="text-align:center;">
{{#tag:gallery|
