How to add inline images

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

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?
