These are the raw pictures for use in the Iowa newspaper ad. 
You are welcome to use any of these images for any Ron Paul promotional purpose. 
The file name format is: 
rpa_1515_100x101x40.jpg
Where:
rpa = image version, rpa is the profile pic
1515 = number of unique pictures in the image (higher is better)
100x101x40 = 100 cells high x 101 cells wide x 40 pixels (square) per cell. 

All images will be at 200dpi in this folder. 

Dimensions can be figured by multiplying the 3rd number by the first two, for example 
100x101x40 is a 4000x4040 pixel image. (about 20 inches square)

Enjoy,
