The term “image macro” originated on which comedy forums?

The term “image macro” originated on the Something Awful comedy forums. In the early 2000s, the site used “macro” for a short piece of text that forum software automatically converted into predefined image code.

The word came from the broader computing idea of a macro: an instruction or rule that expands a small input into a larger output. On Something Awful, the term became associated with pictures carrying captions, a format that later became one of the dominant forms of Internet meme.

The familiar image macro often places large, high-contrast text above and below a picture, frequently using white lettering with a black outline. Popular examples eventually included advice animals, reaction images, and lolcats. These formats spread far beyond the original forum communities during the 2000s.

Something Awful did not invent every captioned picture or every meme image. Rather, it is credited with popularizing and naming this particular forum-based format. That distinction explains why the answer is Something Awful rather than a later social-media platform.
