You will have to use some sort of photo image program to resize them. Check the disks that came with your digital camera for tryout versions of Photoshop.
About your 19's: What kind of spacers did you have to use to prevent rubbing, or do you have some rubbing on the front wheels?
the wheels are super super light. i dont know the exact weight though.
no spacers were needed. the rear off set was like 47 mm, and i think the front was 54mm. 19x8.5 and 19x9.5.
first i had them put it on and the car look weird. there was too big of a gap in the well. so i installed eibach springs and it drop the car about 1.3 inches. no rubbing and drives smoother and tighter.
