The reason an image does not show up in     when uploaded is because the     namespace is not part of the content namespaces array. However, when that file gets added to a page that is part of the content namespaces array, that transaction will hit   .

In contrast, Special:RecentChanges lists every transaction regardless of namespace.

P.S. You’ll notice that Special:RandomPage only cycles through pages in the content namespaces.
