How can you change the size of the picture on the camera?

I want to change the pixel size so when I download my pictures onto my computer, they aren't so big.

I might be wrong about this as I haven't handled this camera in awhile, so let me know if this doesn't do the trick. But I think that the button on the bottom left of the controls on back- the same button you use to delete photos when in Playback mode- will change the photo size while the camera is in Record. So set it to Record (just as though you were about to take a photo) and push that button, it should let you scroll through the options of the various image sizes and then push it again to select the one you want.

Also, if you don't already, I highly recommend using an editing software- that way you can change the image sizes etc. on the computer too. The camera probably came with a simple software you can use, or if you have another one that you like it will be compatible with your camera images as well.

okay, that changes the physical size, but it doesn't help change the amount of bytes in the picture, so it still takes up just the same amount of room in memory.

Frankly, I'm at a loss as to why it even matters. Unless your computer has space issues on the hard drive. But even then, once you get them on the hard drive, you can burn them to a CD or DVD and take them off again. Understand that trimming or lowering the MP of your pictures dramatically alters the quality of the resolution. Why do that when you can simply save the original onto CD and store it?
