I'm working on a blog system that currently reads .jl.md files (posts) from a directory and renders them. But now I'm running into the problem that I want to add certain attributes to specific images in a post, but can't. Is there a proper way to handle this?

I believe Genie uses Markdown.jl to parse markdown files. The package hasn't been updated in a long time so I'm not sure about what it can do
Here's where Genie renders the Markdown (line 611): https://github.com/GenieFramework/Genie.jl/blob/188eea4144e6a03a7465cf2d818b8a3c20c17625/src/renderers/Html.jl#L599-L603
