This Is A Self-Referential Problem

Pyth - 21 bytes

Simple to do with pyth's i base conversion. Takes input as PBM file name and reads using ' command. I had to use !M to negate blacks and whites. Everything else is self-explanatory.

Try it here online. (Web interpreter can't read files, so is modified and takes file as input).

With big thanks to Dennis. Try it online

In case you're having problems with the url, this is the input I tested:

I used the format that GIMP generated when exporting as ASCII pbm, with the comment removed.

Explanation:

l,    read the first line ("P1" magic number) and get its length (2)
l~    read and evaluate the second line (106 17)
q     read the rest of the input (actual pixels)
:~    evaluate each character ('0' -> 0, '1' -> 1, newline -> nothing)
f*    multiply each number by 17
/     split into rows of length 106
W%    reverse the order of the rows
z     transpose
e_    flatten (effectively, concatenate the lines)
      now we have all the pixels in the desired order, as 0 and 17
b     convert from base 2 "digits" to a number

Python 2: 133 110 bytes

A first attempt in python using PIL:

from PIL.Image import*
j=open(input()).load()
a=k=0
while a<1802:k=(j[a/17,16-a%17][0]<1)+k*2;a+=1
print k*17
