.pld = PhotoLined image Document (Googled)

Guessing it's pics of your cars / replays / in race snaps stuff like that

Most of mine seem to be jpegs (when viewing saved pics on laptops gallery) but I've not been into the data files to view what is there, they may be .pld then saved onto laptop as jpeg

Hope this gives an idea of what they could be, I'm not a tech wizard guy to know about this stuff, Google is a good friend :)
