The exact instructions for the program were

The pixels in the above image are numbered 0..99 for the first row, 100..199 for the second row etc. White pixels represent ascii codes. The ascii code for a particular white pixel is equal to the offset from the last white pixel. For example, the first white pixel at location 65 would represent ascii code 65 (‘A’), the next at location 131 would represent ascii code (131 – 65) = 66 (‘B’) and so on.

The text contained in the image is the answer encoded in Morse, where “a test” would be encoded as “.- / – . … -”

You have 15 seconds time to send the solution.

Now of course it says you have 15 seconds which is true and I did do it in 15 seconds, but since this site uses Javascript to count, you can simply disabe javascript to have unlimited time by using the Firefox plugin NoScript.

For example, the image I used was:

which gave the following numbers:

45 46 46 32 45 46 46 32 45 46 46 46 46 32 45 45 45 32 46 45 32 45 46 45 32 46 46 46 32 46 46 46 46 32 46 45 45 45 45 32 46 45 32

which was translated in the following ascii characters

-..  -..  -….  —  .-  -.-  …  ….  .—-  .-

which produced the following output using Morse code to translate:

dd6oaksh1a

The code that I used to program this was:

import Image
def multipleReplace(text, morse_code):
    for key in morse_code:
        text = text.replace(key, morse_code[key])
    return text
morse_code = {' .- ':'a',' -... ':'b',' -.-. ':'c',' -.. ':'d',' . ':'e',
            ' ..-. ':'f',' --. ':'g',' .... ':'h',' .. ':'i',' .--- ':'j',
            ' -.- ':'k',' .-.. ':'l',' -- ':'m',' -. ':'n',' --- ':'o',
            ' .--. ':'p',' --.- ':'q',' .-. ':'r',' ... ':'s',' _ ':'t',
            ' ..- ':'u',' ...- ':'v',' .-- ':'w',' -..- ':'x',' -.-- ':'y',
            ' --.. ':'z',' ----- ':'0',' .---- ':'1',' ..--- ':'2',
            ' ...-- ':'3',' ....- ':'4',' ..... ':'5',' -.... ':'6',
            ' --... ':'7',' ---.. ':'8',' ----. ':'9'}
im = Image.open("C:\PNG.png")
size = im.size
width = size[0]
height = size[1]
L = list()
last = 0
#The loop transforms the image into a list
#If the pixel is white, return 0, otherwise return 1
for i in range (0,height):
    K = list()
    for j in range (0,width):
        checker = (int)(im.getpixel((j,i)))
        if(checker == 1):
            K.append(1)
        else:
            K.append(0)
    L.append(K)
ascii = list()
count = 0
for i in range (0,height):
    for j in range (0,width):
        if(L[i][j] == 1): #determines if the pixel is on
            char = chr(count-last) #converts the distance
            #between the pixels to ascii
            if(char == " "):
                char = "  "
            ascii.append(char)
            last = count
