Great Search This!
yep! just did a search on "oil worker" up comes a few and some shepherds minding the flock, sail-mending and Vincent-van Gogh. then did a search on "refinery" up comes a few with the refinery so far back that all one can see is the horizon and then comes, a great shark and fisherman, a blue pastry and then plenty of jet-fighters with some refinery in background.
Well, its called spam! another reason why somebody should check just what on earth people are keywording.
Oh well, just making conversation really.
