Ahhhhhhh.... I have to respectfully disagree about the "fit to frame" choice ... it really depends on your images' aspect. Most of the sensors in the newer cameras have a 3:2 aspect. When you use fit to frame as your scale choice the image stops resizing as soon as the first two sides of the image are the same as two sides of the show ... in this case that's the top and bottom of the screen. As such, if your image is set to 100% zoom, there is going to be empty space on each side (18.52 total or 9.26% on each side). If it were FILL SCREEN, the image scaling stops when the last 2 sides of the image are the same as the screen. In this case, about 18.52% of the image is outside the top and bottom of the screen (9.26% on each).
While I don't have a specific treatment of aspects written up yet (it's in the queue), I do have the equations available that are relevant to calculating the amount of an image that will either overflow or underflow the screen frame (but, that's relevant only for those who want and need precision placement or for those who need to know specifics). So, the choice of scaling your image will depend on that of your image(s) and what you are trying to do in the show's screen real estate that's available to you (be it 16:9 or 4:3).
Aspect can be confusing, that's for sure. Once you get the basics of it, however, things start becoming clearer. It doesn't help that we've got images and videos of all different sizes and they generally are not the same as the show's aspect. And, If you crop your images to fit your show's aspect, you have to know what you are doing (or you can mess the image up) ... and you have to know how to do the math (or find the right application that does the work for your). PSP's crop feature is non-destructive and easy to use ... but not intuitive and it's not all informative either.

Sorry, forgot to add the link to those layer equations mentioned above. The equations associated with layers zoom, pan, rotation center, height, and width are here:
