Creative hairstyling, you might say, in stock pictures (4,3)

I believe the answer is:

clip art

'stock pictures' is the definition.

I don't understand the rest of the clue.

(Other definitions for clip art that I've seen before include "Widely used images" , "Graphics files" , "computer images" , "Pre-drawn pictures usable in computer packages" .)

I've seen this clue in The Independent.
