Cool web copy regularly having picture of American West? (6)
I believe the answer is:
cowboy
'picture of american west?' is the definition.
(1958 western film)
'cool web copy regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'cool'+'web'+'copy'='coolwebcopy'
The alternating letters of 'coolwebcopy' are 'COWBOY'.
'having' acts as a link.
(Other definitions for cowboy that I've seen before include "(Gun-toting?) untrustworthy workman" , "Artisan doing shoddy work" , "Wild West character" , "Hired hand who tended cattle in the old west" , "Cattle herder of the American wild west" .)
