A DMCA notice is a waste of time unless the site is a/ hosted in the US, since it's a US law (Adultwork isn't, but the ones mentioned may be, for those not on a BlackBerry and who can check) and b/ you own the copyright to the pictures (ie if you took them, although if they were snaps taken by a friend it would be hard to prove otherwise as you could say they were on timer).
Contacting Adultwork should be your first port of call, since this breaches their terms of use. The hosting company and Google should be next.
