Trucks for back scenes?

Hi,

I have been using the RM club container kits to make a back scene for a small container terminal.  Now I need get some pictures of trucks, etc. to go on there as well to give it a bit more depth and suggest that there is space between the edge of the layout and the containers.  Does anyone know where I can download pictures of lorries, stackers or other vehicles in OO gauge?  My layout is based on the early days of privatisation so ideally the trucks would be of that period but I am not going to be fussy!  Any help appreciated.    I have attached a picture of what I have managed so far using the unmade container kits to form a back scene to hopefully show what I’m talking about.
