Entry #25 to the Library is a doozy. Introducing my ‘Micro.blog Multimedia Uploader’ shortcut:

This shortcut helps you to upload any file(s) to your Micro.blog account and then copy the resulting URL(s) in the format of your choosing — including Markdown for images, HTML for videos and audio, or a plain URL for other files.

It includes niceties like allowing you to choose to upload images as either JPEGs or PNGs […], recursive encoding of videos […], and an optional function to use another shortcut to auto-generate image description[s].

Get it here from the HeyDingus Shortcuts Library.
