''set up''

[jctgf]

''this incredible picture is not a coincidence. it's a set up, indeed!''.
hi,
is this sentence ok? is ''set up'' the best option here?
what i would like to say is that one didn't take that great picture
because they were at the right place and time when something
happened. they have, indeed, ''fabricated'' the picture.
just like that famous lock ness monster picture or the big-foot video...
thanks.

How about:

''This incredible picture is not authentic; it's staged, a set up, indeed."
