[Commentor] LC-405 Zev Blut [Comment] 5.4.6 Image Size [IMAGES_SPECIFY_SIZE] Are there actual examples where not setting the width and height of an image actually hurts the display of the image by the browser? I am not so sure how necessary this is, especially when considering that providing this information increases the size of the page. [Working Group decision] We have clarified that specifying the intrinsic dimensions of an image allows that the browser doesn't have to re-flow the page in the course of displaying it (re-flowing creates usability problems due to changes of focus, and also may have a bad CPU/battery impact).
