Hey,
I never tried actions...
I do all my galleries by hand cause I just started out. I make like one gallery a week max cause I just dont see the sales happening and I dont wanna pay for hosting and so I use bestsexhost...
Go check out some good Photoshop related sites like:
http://www.designsbymark.com/ - Nice forum.
http://www.phong.com/
I had more links but lost them all when I formatted. I will get back to you tommorrow with more info...
