How to get the google chrome themes up?

I know how to get the themes and how to install them but i have a lot installed on my computer and the one that I actually want to have for my theme i cant find it on my computer. If you can help me find out where to find the files to change my theme that would be a great help.|||Alright, the themes dont actually download onto your system. They simply download and set within the browser. If you want to pick out your themes and change them, go to the drop-down menu Chrome-%26gt;Preferences...-%26gt;Personal Stuff-%26gt;Click on the bottom one "Get themes" under themes. There you go :)|||you search by www.google.com
