Micro.blog did this nifty thing to make a Photos page (or, it still does; I’m just not blogging there anymore) by looping through all your posts with JPGs in them (under the idea that PNGs probably were screenshots, not photos), grabbing the first photo from each post, and making a gallery out of them; each photo linked to its corresponding blog post. Today’s project: explore how to do something similar in WordPress, especially if I somehow can get it to use Jetpack’s tiled gallery format.
