I had my photo taken at Costco and it took about ten minutes, if I recall correctly. Cheap too.

We had my son's photos taken at a drugstore for about half the price of the ones at the post office's passport office. Most places that offer one hour film processing have a set-up for doing passport photos. It only takes a few minutes.

Thanks for the advice, Heavens and Orcas. Even tho' $15 doesn't seem that bad, since there are four of us, if I can get it for half that, so much the better! A little extra money to spend on the trip!
