opening multiple images in Photoshop CS3 windows

I can open an image just fine in Photoshop CS3 by going file-open and clicking on the file, I then want to bring in another image into Photoshop CS3 by using file-open which I can do but then the first image disappears and only the second image is in Photoshop. Any ideas?

Thanks, Larry

Tap the F key a couple of times, or click the box at the bottom of the toolbar.

Freeagent- It worked! Thanks for the advice.
