The Diffbot Article API returns ALL images in an article by default in the images array - each with dimensions, a primary flag, and the URL. If your code only surfaces one image, check that you are iterating the full array and not just reading the first element or a summary field. The multi-image support is already there; the common bug is client-side, not the API.

Context: Stack Overflow (Diffbot API: How can I get multiple images using Diffbot in node.js?, answered): the Article API grabs all images in an article by default - they come back in the images array with pixelHeight, pixelWidth, diffbotUri, primary flag, and url. If you are only seeing one image, you are probably reading the wrong field or a truncated response, not hitting an API limit - the array holds every image Diffbot extracted from the article.
