Missing dungeon tile images

I discovered this while practicing in the APIs to get a better understanding of how to use the game data.

If you retrieve media data for a dungeon (via /data/wow/media/journal-instance/), the one entry you seem to see every time is something like this:

‘key’ => tile
‘value’ => ‘render-us.worldofwarcraft.com/zones/blackrock-caverns-small.jpg

Most of those images work just fine, but I have noticed that several return “403 Forbidden” … I cannot imagine that this is working as intended, so I’m posting the ones here that generate the error:

It’s a lot, but there’s a lot more that work just fine.

(Per Schiller’s suggestion in another post, I improved the readability of the non-linking links.)
