All Devices Relative file links in iOS

[pja2536]

I use MultiMarkdown for almost all my writing and document preparation. On my iOS devices I use 1Writer as my editor and MarkDown previewer. A major issue with this is that I can't get images to display inside a Markdown document.

Some of the link types I've tried are shown below:

# Four images should appear below!

### Image link


### Image link (local)

![Emissions are from fuel combustion and include road-sector emissions. Best, Burke, Jotzo 2020][img1]

[img1]: Carbon-Pricing-Works.jpg border=2px width=700px

### Image link to the original file using Markdown syntax


### Image link to the original file using HTML syntax

<img src='https://images.theconversation.com/...0&q=45&auto=format&w=600&h=414&fit=crop&dpr=1' alt='Emissions are from fuel combustion and include road-sector emissions. Best, Burke, Jotzo 2020' border=2px width=700px>

The two links that use the original (web-based) image file work. The two that try to access a copy of the image in the same folder as the Markdown document do not work.

It seems that I am getting the relative file link within iCloud/Files wrong.

Can anybody please suggest a fix (other than ditching Markdown).

Peter
