Do you know how to set up actions??
They're dead easy, I use them for copyright, saving, resizing, watermarking..
When you have your image open, click on the actions tab (with layers/history, on the right hand side unless you have it somewhere else), click on the tiny drop down arrow at the top of the actions pallet and click on new action (this can be put in a 'new set' too to make it easier to find amongst the adobe default actions), then name it, and at the bottom of the actions pallet, click on the record button. Then, go to file info, fill in the owner, copyright info and all that jazz, click Ok and then click stop in the actions pallet. easy peasy and you don't have to bother doing it every time, you just open up your next photo, choose the action and click play
Hope that's useful!
