If you mean pictures of CDP use at the front, its use there was mainly confined to British Sextons. The Canadian Army Overseas did not like it much, as it wore out the tires and idler bearings, and tended to shed, if not kept properly tensioned. As a result, Canadian Sextons and Ram Kangaroos that served in NW Europe did not use it. I devote about four pages in my forthcoming book on the Ram to the CDP saga (it should be out in May "Canada's Pride - the Ram Tank and its Variants"
www.servicepub.com).
DND's Director of Armaments summed it nicely - CDP was an excellent track, but unsuitable for use with M4-type suspensions or running gear.
Here is a Ram with CDP being tested in the UK in early 1945
