Three Sips of Gin by Tim Bax has photos, but not in super great quality. Mostly black and white in the paperback I have.
Bush War Operator by Andrew Balaam has photos as well, in better quality IIRC.
I'm pretty sure We dared to Win about the C Squadron, The Rhodesian SAS has a ton of color photos.
Basically, your best bet are books. There's a lot of pictures in memoirs that come from personal collections.
