Which flower is pictured?

Interesting. The chamomile I'm familiar with doesn't look like that. It's a small plant with little yellow balls (instead of daisy-like flowers).

This photo is a daisy. The camomile looks similar, but petals are smaller and more rounded.

this looks like a Marguerite daisy. the camomile I know is much smaller and has a more yellowish tint on the petals
