Images that appear in Hypertext Markup Language from a remote source.
Images that come from a remote source instead of the home server where the html is hosted ... <img src> (Image Source)
To save room in a blog that uses basic HTML editor software, the images that are referred to in any given document can be stored in a remote location, another computer or in a cloud storage format.
I had to give this some thought. The writing sites that let you upload images that are stored in your home computer using your browser's upload feature or the writing site's uploading software may in some cases use HREF in HTML to allow viewers to see your images in the documents you publish but not from their server, but instead from a remote source, your PC.
Or not. I have to Google search this for a minute and link to an article that is related to this subject of HTML remote source images not from the same source as the HTML document on the server itself.
