Answer

"Έξη" is a word that was used in the ancient language and it comes from the verb "έχω" which means "to have". 
Έξη is a habit that got acquired due to the repetition of an action, or it can mean possession of something. So it has nothing to do with its homophone "έξι". 
Plus, as far as I know we don't use "έξη" in today's language at all.

The correct word is "ζωγραφιά".
