There are a bunch of actions you can use to do some basic adjustments to photos which are just clicking a button but Photoshop is huge and eats your ram.

I found a batch editor last time. I came back from Sydney with 800 photos from a day shooting family photos for someone.
I ran them all through the batch editor and only played about with about 40 myself.

It's so time consuming though.

All the photos I put up on flickr are small versions because I just don't have the bandwidth to do it. I don't have a paid flickr yet either but even if I did our uploads count in our monthly 12 gig and it only lasts two weeks of the month as it is. I'm so sick of being on dial up speed.
