I will search out 5 photos on 500px as described by you.
500px is a large community and photos are grouped according to creative commons licenses.
I would recommend to use those allowing commercial use. these photos are excellent for references and reaching out to far flung places.
I will not provide the photo, what I will do is to give you the link to the photo to find it on 500px
the photographers' profile will be available.
I will pick 5 photos for you according to your description
for example the photos may relate to
+ things like cars or pots or doors or streets
+ birds and animals
and everything else ! just use your imagination.
