Chrome images are small within Tables

I am using tables to display images/text on pages in my website. My problem is that the images appear much smaller in Chrome and from reading online, it seems that it is a Max-Width: 100% issue?

The problem is that I am fairly new to HTML/CSS and I need a little help to change the code to prevent this issue from occurring. A link to my page is listed below:

If you review the page, the images sizes are correct in Firefox and IE, but not in Chrome.

I’ve seen a few different options, but every I attempt to change the CSS it doesn’t seem to have an affect. I’m not sure what code change I should use and where it will be changed on the site…Please HELP!

-Thanks in advance!
