You can embed videos from MEGA, but not images. Or I don’t know how to embed images. With a video, you just right click on it, and click embed.

Maybe only some image formats allow that.

Perhaps you can replace the URL for the iFrame for the video embed, with an image URL.

Appears to be no way to embed images, like videos. Too lazy to replace the URL in iFrame and see if it works.
