You can do this by inserting a html image tag into the name input field for a particular store location. So, this is what you'd add:
<img class="result_image" src="####"/>
And then you'd replace #### with the images file pathway. For styling purposes, add this to the "page header HTML" text box in the apps display settings:
.result_image { float:left; margin-right: 10px; height: 100px width: 100px }
This will cause the image to be a square. If you'd want different dimensions you would just change the height/width values in the code above.
