That should do it.
In XP, there is a viewer utility which is way better for just looking at pictures than Elements built in, called Windows Picture & Fax viewer. It doeasn't take up much memory and you can flick throught photos with the arrow keys. I'm sure there must be something simimlar in mac-world.
If you change the default program for picture files to Elements, every time you want to look at a picture, Elements will open. It's good, but it isn't a very good viewing utility, it's an editor.
Best idea is to get a free viewer utility to view, and open pictures from within Elements to edit.
That's the way I do it, and I try not to do things the hard way.
