Comment:

This challenge is the first in a row of (way too many, in my opinion) challenges that require the Python Imaging Library (PIL). If you chose to solve these challenges with Python, that is. I suppose even ImageMagick and a shell script would do the job in some cases.

Possible Solution:

import re, Image

i = Image.open("oxygen.png") # http://www.pythonchallenge.com/pc/def/oxygen.png
row = [i.getpixel((x, 45)) for x in range(0, i.size[0], 7)]
ords = [r for r, g, b, a in row if r == g == b]

print "".join(map(chr, map(int, re.findall("\d+", "".join(map(chr, ords))))))
