Glad it worked for you. I use this all the time at work. Its a great time saver when I am working on car ads with lots of cars. I get digital photos usually of the cars and just put them in a folder and I have several different actions setup to cover various sizes. My actions just resize the photos and apply a tag line in the metadata so the photos go to the right place in our database when I send them to be processed by our imaging system.
Good idea on the tutorial... I will mark that on a list of tut's I am putting together this fall/winter
