Only twenty five of the 244 pictures I have scanned were marked with captions. Below is a list of those twenty five. I am assuming the captions were written some time later (perhaps many years after the war) due to some inconsistent dating, see caption for ww2_012. All captions are written in block capitals except those noted. The text within the brackets is mine.
ww2_002 - "D.E.M.L."
ww2_003 - "D.E.M.L. ; about to leave for desert center"
ww2_004 - "D.E.M.L. '42 Mess Hall"
ww2_005 - "Salton Sea, Calif"
ww2_007 - "Bill Bauman '42"
ww2_008 - "Camp Cook[e], Calif"
ww2_009 - "Camp Cook[e], Calif ; Laundry"
ww2_011 - "Los Ang[e]les Calif"
ww2_012 - "Loaded up for the drive from Camp Cooke to Tenn. Man[e]uvers 1942" [The date here is probably incorrect. Other records indicate that he remained at Camp Cooke into the next year, beginning maneuvers at Ft. Knox in late March, 1943.]

ww2_149 - "German-__[?]__ Border" [most of the 1st and all of the 2nd word are cropped off]
ww2_160 - "Ohagan, Lighten & ?"
ww2_166 - "John T. O'Hagen" [I am not sure of the correct spelling of the last name here, it is spelled slightly different on other images, see captions for ww2_160 and ww2_243]
ww2_243 - "John t' O'Hagan The best Irishman and friend I believe I ever had." [neatly printed in upper and lower-case]
