Most of you prolly' already know this, but I've read where some were having trouble in this area. This is intended for those who aren't as compuer savvy.
GOTO: START
THEN: All programs/accessories/paint
THEN: FILE, OPEN.
Browse until you find the pic you want,and load it.
In PAINT:
GOTO: Image
On the drop-down, choose "STRETCH/SKEW"
In the stretch options, change the percentage from 100% to whatever you need. (i.e. 66% will reduce original by 1/3rd. Make sure you put the same values in both the horizontal and vertical boxes, otherwise yer pic'll look funny.
Hope this helps!
