I dont think that's the exact origin. Look at the file name from Q. It's DUGtJVsU8AElqAt.jpg-large.jpg, which the letter after U8AE either a lower case L or an upper case i.
Need to find out where he saved it.
I think he either wants us to find out where the file came from, OR, he accidentally released the file without changing the file name. Not sure if we should pursue this in risk of doxing Q, or if we should in hopes that this is what Q wants.
