Please help me with image size issue.

I created the website but when I upload it in a server. I see that the image which is the logo has a different sizes in different browsers for example, it is very large on Chrome but it will be in a normal size when I refresh the browser and it is very small on Safari and I still do not know how to solve it but it works okay on Firefox.

This is the responsive website. Here is the link http://kclarkwebdesi...site/index.html

Thank you for your help.
