IMG

Internet slang shorthand for 'image', derived from the HTML image tag (img src=...) used in web coding. Online it is used casually to refer to a picture or image file, particularly in forum and social media contexts. Also used as a file extension (.img) for disk images. The internet slang sense is simple, widely understood, and has been in use since the early web.

Short for 'image', IMG is internet shorthand used across forums, chat platforms, and social media to reference a picture or image file. You'll see it in markup tags like [IMG] on old-school forums, in filenames, and in casual conversation when someone's about to drop a photo. It's one of the most basic building blocks of internet communication — the three-letter code that holds the visual side of online culture together.

(internet slang) An image.

(file format) A disk image of a file system.
