In reply to Satrya.

Wow! Picjumbo is awesome, thanks for the heads up on that @satrya. Do you know if the images on Picjumbo are CC0? It's not very straightforward on his site and I emailed him and he didn't give me a clear answer on the exact licensing. Here was his response:

"Thanks Matt! There is no licence, check out Terms & FAQ in the left menu :)
Cheers!
Viktor Hanáček"

I want to use some of these images but only if they are CC0. Would you think that his reply means they are CC0?
Thanks,
Matt
