Markdown

Just wondering if there is any way to use metadata tags in markdown links? At the moment this markdown: ` Becomes, this HTML: <img src="/%7B%7Burl%7D%7D_images/picture.jpg" alt="caption"> The brackets just get encoded. Can this be avoided? Or should I just use HTML to start with?

Is there a way to link a pdf file located in the same folder of parent note? Because at the moment I can link only pdf in the root 'Files' folder

How do I get markdown to display an image caption?

This is used about two minutes into the demo video on Blot's homepage

I am learning Markdown and today I tried to add an image but it went pear shaped. I looked up the basic code for adding image but I cannot get it to work. It will be a local image on my drive.
