Why publish the links if it's not public and can't be seen? 
Lol, I thought that since they're all repins (namely saved from other, public, boards) the individual links would have been public. Sorry about that.
This looks suspiciously like spam to me.
I assure you Dioxine that, even if in a rather clumsy way, I was just trying to help. You might not want any, but the original poster asked specifically for graphic material sources so:
I went ahead and grabbed the original links of some of the pictures in the aforementioned board:
