Online image of huge dimensions? (4)
I believe the answer is:
epic
'of huge dimensions?' is the definition.
The definition suggests a singular noun which matches the answer.
'online image' is the wordplay.
'online' becomes 'e' (abbreviation for electronic, e.g. in ecommerce).
'image' becomes 'pic' (short for picture).
'e'+'pic'='EPIC'
Can you help me to learn more?
(Other definitions for epic that I've seen before include "Great movie" , "Impressively great" , "Long narrative poem telling of a hero's deeds" , "Large-scale" , "Impressive scope" .)
