How to add inline images

This is a tutorial I found that teaches users how to insert images in gemlog.

=> gemini://miso.town/inline-images

It is not possible to view the images directly in gemlog, but you can jump directly to the page to view them.

But since I'm not a technical-savvy, I used a somewhat dumb method myself. That is, upload the image I want to use to this site, then get the link to add it to my text.

I still haven't figured out how to get the images to load and display directly in gemlog:(

Is it because the server I'm using, gemlog blue, is too simple?
