Picture house and record memory (8)
I believe the answer is:
hologram
'picture' is the definition.
(hologram is a kind of picture)
'house and record memory' is the wordplay.
'house' becomes 'ho' (abbreviation for house).
'and' means one lot of letters go next to another.
'record' becomes 'log' (logging is a kind of recording).
'memory' becomes 'ram' (RAM is an example).
'ho'+'log'+'ram'='HOLOGRAM'
(Other definitions for hologram that I've seen before include "Three D image" , "Three-D laser image" , "Photo" , "Three-dimensional image created on film" , "3-D image" .)
