Hi,

I see — you want to read Markdown files outdoors, and images don't show properly unless you tap them. That's a known bug on the mobile app.

Open the file in Safari (tap share icon → "Open in Safari") — images should render fine there.

You can also report this to GitHub here: https://github.com/github/feedback

Hope that helps!)

If you need to read Markdown files comfortably on your iPhone:

Open the repository/file in Safari instead of the GitHub app.
Safari generally provides better Markdown rendering and image loading.
For the outline specifically, GitHub's web interface has better navigation support than the current mobile app.

If you're trying to fix this as a developer, the actual GitHub Mobile fix would require adding a Markdown outline/TOC component to the file viewer and fixing the image-loading/rendering lifecycle so images are loaded when the Markdown view appears rather than only after interaction.

The discussion itself is essentially a feature request + bug report, not something you can fix through a GitHub repository setting.
