Enlarge default screen size of opened photo files

Question

When I drag a photo file to Photoshop, it opens in a size significantly smaller than the workspace. (This is especially true with vertical [portrait] photos.) Therefore, every time I open a photo (and I do this typically hundreds of times a day...), I have to drag the lower right corner way out to enlarge the frame, and then I have to scroll the mouse wheel to make the picture expand to (approximately) fill the frame. Only then can I see it well enough to make the required ajustments to the file. Isn't there a way to tell Photoshop how large I want the photos to appear in the workspace, so it opens every new photo file to the same size?
I am using Photoshop CS (not CS2 or CS3).
Thank you for your help!

Vincent,
As Norbert says, Ctrl+0 makes the image fill the screen.  That's the same as going to the View menu and selecting "Fit on Screen."
Here's a slick little trick that I think I read about on the forum some time ago.  (I doubt I figured it out myself.)  You can use the PS Script function to automatically size an image to Fit on Screen whenever a new image is opened.  Here's what to do:
Create an action that has Ctrl+0 in it.  To do this, open an image, start recording an action and click View>Fit on Screen, then stop the action.  Name the action something like "Fit on Screen."
Go to the File menu and select Scripts > Scripts Events Manager.
Click the little checkbox at the top to enable scripts to run.
In Photoshop Event, select Open Document.
Click the radio button for Action.   Navigate to your new Fit on Screen action.  Click the Add button.  You should now see your script in the white box under the checkbox at the top of the dialog box.  Click Done.  That's it.
Now, when you open a file, it will open in the size you would get if you manually pressed Ctrl+0 or View > Fit to Screen.
If you like how changing the screen mode looks -- with an image open press the F key 2-3 times -- you could always add that to your action so you image will open large and in the mode you like best.
Hope this helps.
