How can resize photos on the landing page?

Im testing Jobs & Experts at the moment. Please tell me how I can change the size of the experts' photos on the jobs & experts landing page?

I would like mine to look like your Jobs & Pros site.

In fact, I like all of the customizations you made to the theme on your Jobs & Pros site.

I know this is a stretch, but would it be possible to get a list of changes customizations and selected option that were made to the theme to make the Jobs & Pros site look like it does?

Thanks in advance

Jay
