Hi Staci....you can usually save your pics at a lower resolution in the program you use to transfer the pics from your camera to the computer....this will reduce the size as well. Usually, reducing the resolution one or two notches really doesn't reduce the quality of the picture itself.
Microsoft Office (photoshop) also has a resizing option under "image". Just use the little arrows, shrink, SAVE (learned that one the hard way LOL) and then check your properties again.
