Flaps from article appearing in illustrations (6)
I believe the answer is:
panics
'flaps' is the definition.
(getting into a flap is getting into a panic)
'article appearing in illustrations' is the wordplay.
'article' becomes 'an' (indefinite article).
'appearing in' indicates putting letters inside.
'illustrations' becomes 'pics' (pictures).
'an' placed inside 'pics' is 'PANICS'.
'from' is the link.
(Other definitions for panics that I've seen before include "Loses the head, takes fright" , "Loses one's head" , "Gets into a sweat" , "Yields to fear, loses the head" .)
