I'm still not gonna qualify the images as being fake, if only for the fact that it's the most coherent lead that we currently have. Notice that there are no zero's in the set of digits. It is extremely unlikely that a pseudo-random (for example an encrypted string) set of 36 base 10 digits would contain no zero's. I personally interpret the 4 bathroom images this way: the set of 36 digits should be chunked in four (the number of drawings in the bathroom) groups of 9 (the number of greenish bars in each drawing) digits. Each digit (or bar) is construed from 2 entities of data each (as indicated by the 2 lines that lead to every bar). Possibly we have to factorize or otherwise disassemble every digit into 2 digits. These 2 digits may be either constant for every digit in the 36 digit set (this logic can be inferred from the drawings if you interpret each 2 of the convergence points as being 2 constant integers which could somehow be used to generate each digit), or dynamic, ie. a different set of 2 numbers each resulting in a certain digit). For the latter alternative factorization is an option. For instance, the first number in the 36 digit set is '6', which can be generated by either multiplying 1 and 6 or 2 and 3 (thus 1,6 and 2,3 being the two digits that are the two convergence points in each drawing). Given the rather extreme improbability of the lack of zero's in the 36 digit set, they might be hinting at multiplying two positive integers (greater than 0) to yield each digit, or either way some formula that would never yield a zero.
Just thinking out loud, everything could be fake and I might be wrong, I realize that. But I'm not so much desperate to unearth the new album title as I'm a sucker for number puzzles
