The Irish love hothead in photos and artwork (8)
I believe the answer is:
graphics
'artwork' is the definition.
('graphics' can be a synonym of 'artwork')
'the irish love hothead in photos' is the wordplay.
'the irish love' becomes 'gra' (I can't explain this - if you can you should give a lot more credence to this answer).
'hothead' becomes 'h' (head letter of 'hot').
'in' is an insertion indicator.
'photos' becomes 'pics'.
'h' inserted inside 'pics' is 'phics'.
'gra'+'phics'='GRAPHICS'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for graphics that I've seen before include "Letterings and drawings" , "Illustrations, drawings" , "Drawings and photographs in printed publication" , "Computer images" , "Artwork" .)
