I’m a new user and don’t know how use Obsidian yet. I wanted to know how to place an image inside a link to serve as a cover.
Depending on what you mean by putting an image inside a link, there’s two things you could do. An actual embedded, clickable image is a bit convoluted, though.
This will embed the image, but not make it a clickable link:
![[/path/to/image.jpg]]
This will embed the image and make it a clickable link, but only in reading mode or as an exported document:
[](https://www.example.com/)
If you don’t want the alt text for the image, you can just use empty square brackets for that part, []
Below an example for what Marionette explained.
There is a wonderful Documentation. These things and more are explained there. For example how to resize images or embed PDF-files. Hope it helps
