GIF or JPEG, for example (5)
I believe the answer is:
image
I believe this is a double definition.
'gif or jpeg' is the first definition.
(I've seen this in another clue)
'for example' is the second definition.
(image is a kind of example)
(Other definitions for image that I've seen before include "Visualisation" , "Idol; simile" , "Mental picture; idol" , "Likeness or mental picture" , "Visual or mental representation" .)
