Extremely unrelated suggestion

While that does the trick, it is not particularly user friendly. I would prefer to not have to navigate away from where I am in the text to learn the name of someone in a picture. As soon as I navigate away the natural flow of reading gets interrupted.

Also, as I generally browse LWN though a mobile device I would also like to not have to eat from my data allowance by loading a large image, when I really just want to have some information that could easily have fit in a small caption.
