Result: Puzzle Solved
I helped my friend solve this puzzle, and I think it's impossible to solve anymore so I thought I would post some information here to help future solvers who are searching for the unintelligible image provided in the cache.
Here are the images:
With some difficulty, I was able to figure out the concept that the two pictures are associated with Forum IDs for two geocachers.
I know the second one is for Road Runner:
http://www.geocaching.com/profile/?id=373120
So 30.8495149 * 373120 = 11510571 which I'm sure will give you the correct answer for the longitude.
The first image seems to be impossible to figure out.. For this, you'll need to guess a Forum ID that gives a whole number when multiplied by 17.48140218.
