You can choose which image to use as your logo in Google search results.
<div itemscope item> <a itemprop="url" href="http://www.your web address.com/">Home</a> <img itemprop="logo" src="http://www.example.com/logo.png" /> </div>
Where it says "http://www.example.com/logo.png", you need to have your logo or photo uploaded to a site like photobucket where you can then get the code for your particular link. Once you have uploaded your photo/logo there you just click on the photo and then the link.
A logo/photo in Google results will often draw the eye to a listing.
Be patient, it make take a while for google to update your listing.
