#2"As I read, numbers I see. 'Twould be a shame not to count this art among the great texts of our time"
Only took about 5 seconds to find.

That is most likely just a hint, or misdirection. I'd be greatly disappointed if it's not a multi layered puzzle.

That's the comment at the end of the file, but is this even the challenge?
Because it take takes less than 5 seconds to find it, i think this is a hint not the solution.
EDIT: Use gimp to save it as ASCII portable bitmap (https://en.wikipedia.org/wiki/Netpbm_format), strip the headers and all the junk and you get a message that links to mi5.gov.uk/careers.

#6Clearly the horizontal span lengths , between each fixed height step, encode a useful sequence.
Numbers. Or an offset sequence. If it's a simple cipher recovery should be quick.
Somehow this whole thing reminds me of Egyptian fractions
How long will hn take to solve if we work together
Okay what if rearranging the red strips so their edges are flush encodes a transposition. Key for the cipher.
I'm betting hn will solve when post is 49 minutes old

I'm fairly certain that's just a hint.

Somehow I doubt that's the solution either, you can get to that same link by just using the Careers menu item.
I would think/hope it's a bit more complicated than that.
Looking at the challenge one of the things that has me wondering is why do they repeat the same text twice, but with different font sizes. This suggests some kind of fraction that is somehow relevant to get further in the puzzle.

It's but read the edit, the solution isn't much more complicated than that either :) this is very basic steganography.

I did, my comment is about the edit. It feels that there should be more to it than that. I would at least expect the result to point to something you can't get at by just browsing around.
Perhaps I'm just hoping for more than there is to it :).
