We have a client who is pretty set in using images of her staff on call to action buttons. I can see how it would build trust for the user to see a face since their service involves speaking to someone to get a custom quote.
Currently they have such button:
The down side as a developer is that I have to work around these images in the buttons and does not allow buttons to be easily changed going forward.
Does anyone know of any stats or articles that talk bout this type of thing so I can get a clear answer as to what is going to be the best call to action.
