This tip applies to both Leopard and Tiger (even Windows and all other platforms). Adobe released Photoshop Express today. It is an entirely free web application. It lets you do basic photo editing as well as publishing to your own Photoshop Express Gallery (and even to websites such as Facebook). I tried it and it is truly a fantastic web application. The editing options are simple, but if you are used to editing with applications such iPhoto, it is really good. If you get in early, you'll also have the chance of selecting your gallery URL before all the good names are selected. You can learn more and sign up here at www.photoshop.com (select Photoshop Express).
