It all depends: how attractive are they?
I believe that photos increase trust with site visitors, but it’s a case by case basis.
Years ago, before Facebook and Twitter, I wanted to put a photo of our team on our site.
There was push back, as people didn’t want their photo on the web. (As I said, it was a different time.)
We looked at getting illustrations done, but it was too much money for our small startup.
We ended up going with kid photos, which has gotten great response from our site visitors, and also shows our irreverent attitude.

In short, use photos if they help establish your brand and build trust.
