Snapchat Sees More Daily Photos Than Facebook

Not really surprised by that.

It's much easier to send a photo on Snapchat than post one on Facebook and they all disappear so obviously absurd numbers of photos will be sent. Not really a valid comparison.

... and now they're all gone. This metric does not matter, as you cannot compare people posting pictures meant to be semi-[permanent, public] with people (primarily of lots-of-free-time age) posting ephemera.

Is Sanapchat being overhyped? it is a little ridiculous to consider it 'safe to be silly', with every modern smartphone have a screenshot option

Only if you count one photo sent to ten people as ten photos...
