I'll try to explain this succinctly, though I sometimes ramble;-) The monitor you are looking at is lets just say 17", displaying 72 dots-per-inc (dpi). Most every monitor displays 72dpi.
The camera is taking pictures at maybe 300+ dpi and they're maybe 1600x1200 lines of resolution. The resolution of your monitor can be 1600x1200 as well, but remember, the monitor only displays 72dpi, the camera image is actually 300dpi, so the camera image is actually many times larger than your monitor in relationship to the monitor's display capabilities.
Picture it this way, if you printed the image on a piece of paper in relation to your monitors dpi, it would be like a wall poster. This is not what you want to email to your friends, and even if you resize it, you will still have quite a large file.
The key is you must change the resolution of the image, not just the size. (In fact, you may not wish to adjust the size at all)
What you can do:
In Photoshop, go to Image Size under the Image menu, adjust the resolution of the image to 72, resize as you see fit. That should result in a much smaller file.
The idea is output. If you would be printing the image, you must retain as much resolution as possible. For email and display on monitors, 72dpi is the key, any more is generally superfluous.
Notice the number in front of the % sign, at the top of every photoshop image? This will let you know how large the image will appear. When you open an image fresh from your camera, it will show at maybe %16, when you email your friends, make the image a pleasant size at 100%.
Hope this helps _AMG
