<Img src="urlhere">
This inputs images to html enabled frames, you can use this on profile pages, comments, blogs, bulletins, and in groups. To be more specific, use Imgur and link directly the image. It won't otherwise show up if it's the share link from Imgur, but uh, for example. When you open to an image with a right click, you can select the image address to replace the urlhere in that code segment. It'll pull the image from the host directly and display like you uploaded it to here.
Ex:
I have an image from a profile on facebook that I own and use, I want to link it here so I upload the image to Imgur to share it, but that's not enough, I want to embed that link with HTML! So here's what we do. On the page you uploaded the image to, right click, open image in a new window, and you have a direct link to that image with the image type on the end. (It will look like a regular URL but with the image name.png or jpeg, or jtif on the end.) You want THAT link specifically to link to your page.
Where I want to place the image, I put in the code snippet above
<img src="https://i.imgur.com/NRGPs9U.jpg">
And hit save all on the profile/blog entry/comment.
The end results, drumroll please.
