Scale a pic in Word 2010, (since my work computer has that)

Open pic in something like paint, trim off margins to bumpers of truck, save as new file.
Open word, hit Insert tab, Picture, select new file
Right click picture, Size and Position
Adjust Size with Absolute to the dimention you set at picture edge.
Hit ok
Print
Verify that it printed out correctly scaled

Hopefully that makes sence, i've gotta go do actual work.
