It is always the case. They are different ratios. An 8x10 is a 4:5 ratio which is more square. A 5x7 is, well, 5:7 which is more of a rectangle..
I had a photo I took with my new TZ1 printed at 5x7 and 8x10. The 5x7looked like the original photo I took. The 8x10 was missing some ofthe image on the outside edges. Why. Is this always the case? Can itbe corrected?..

What was said - they are simply different shapes of paper..
Your camera takes 2560x1920 pixel images, which is aspect ratio of 2560/1920 = 1.33. Meaning, the long side is 1.33 times longer than the short side. This is the "shape" of the image..
8x10" is 4:5 aspect ratio or 1.25:1.
This is a different shape (more nearly square), and it means you must always trim a bit off the long ends for the camera image to fit on the paper. This is simply the shape of the paper..
5x7" is 1.4:1this means you must always trim a tiny bit off the short sides to fit the paper.
6x4" is 3:2 or 1.5:1... longer and skinnier.this means you must always trim even more off the short sides to fit the paper..
These are simply four different shapes, four cases of more or less elongated rectangles..
Technically, there is a way to stretch and distort the shape so that it does fit, but you will not likely like the look of this distortion...
Basically you need to understand proportion and add canvas to the image so it prints without forcing either a resize or crop:http://www.bermangraphics.com/coolpix/digital_print_sizing.htm.
As you increase the size of your print you need more pixels to achieve the optimal photo. You can crop to achieve the ratio of your print, but you need a larger file to print an 8x10 than you need for a 5x7...
BetterJPEG has a function to add whitespace left/right or top/bottom outside the picture so standard printing will print the whole picture, with the whitespace borders. It has standard presets for the standard photo sizes. It is "lossless" JPEG processing and no quality will be lost (except 1 to 8 pixels along one edge sometimes)...
Free Picasa has an easy to use cropping tool that works for common print sizes..
Picasa is a good program for keeping track of photos on your computer and for first-line editing...
