Reverse Captioning

When a screengrab or screengrabs contain text and nothing else^*, instead of doing a caption that adds more text to that in the image (-a 'textcap' ?), one can instead describe an image to which the pictured text forms the caption. This is 'Reverse Captioning' or 'Inverse Captioning', and is not yet extensively practiced. Cf. 'The future of captioning'.

[good examples needed]

^*(an image of text rather than a picture image)
