I built a little extension to Micro.blog that lets you easily add a photo grid to your website. Thanks to @manton for making Micro.blog extensible! – https://github.com/cleverdevil/microgram
@cleverdevil Thanks again for the photo grid code! Do you have any sense of what to tweak to get three columns of photos in the Micro.blog Marfa theme? It only has two columns in that theme vs. three for the default theme—assume this is some minor CSS issue (and no biggie if you don't want to look into it—really appreciate the open source code).
