One impressed by false image, I had nothing subsequently (8)
I believe the answer is:
idolater
'one impressed by false image' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'i had nothing subsequently' is the wordplay.
'i had' becomes 'id' (I'd).
'nothing' becomes 'o' (looks like zero - 0).
'subsequently' becomes 'later' (I've seen this before).
'id'+'o'+'later'='IDOLATER'
Can you help me to learn more?
(Other definitions for idolater that I've seen before include "No orthodox believer" , "I'm devoted to my image" , "great admirer" , "I love a religious image" , "Aaron, perhaps, in Moses' absence" .)
