Speak irritably before attempt to find photo (8)
I believe the answer is:
snapshot
'photo' is the definition.
(snapshot is a kind of photo)
'speak irritably before attempt' is the wordplay.
'speak irritably' becomes 'snap' (I've seen this before).
'before' says to put letters next to each other.
'attempt' becomes 'shot' (shot is a kind of attempt).
'snap'+'shot'='SNAPSHOT'
'to find' acts as a link.
(Other definitions for snapshot that I've seen before include "Informal photo" , "still taken quickly" , "Bit of camerawork" , "Quickly taken photograph" , "pic" .)
