If Pi truly is random and infinite then it contains every possible finite combination of digits, and as such it would contain a combination that, when you put into your 5k by 5k picture, would simply be a black image with the words "Hello Quantum Quack".
It would also contain a combination representing the DNA of every person alive, dead, and will ever have lived. Plus the words to the Bible, the Quran, and every image that could possibly ever be conceived, and more.
But then so would every other truly random infinite number sequence.
It would also contain the sphere that Sagan suggested in Contact.
The only problem for those looking is that the chance of finding those things is mathematically zero, even though they do exist (ignoring the issue of whether the infinitesimally small really is equivalent to zero).
I got a picture of a meat pie, but not able to say beef or lamb
Also no mashed potato or peas
