adding image in the header.php

I am trying to add an image in the header.php. I have uploaded a .png file to wp-content/themes/gamepress/images.

I know where to edit the header.php to get it where I want but i just need the code to be able to insert the image.
I want to set it on the left of the ad banner that i have and the code i currently have is:
<p align=center style=”margin-top: 15px; margin-right: 75px;”><img src=”./images/logo1.png” width=”170″ height=”90″ title=”Logo” margin-right: 10px; />< ad banner script></p>

however the image never shows up.. Did i upload it to the wrong location? is there something more i need for the img src code. Thank you in advance.
