 <p>I had the similar problem, I did the same as you have done and was getting 404 error for the PNG. When reviewed the other requests that are made, I came up with, you must pass the "package name" in the parameter logo as well. </p> <p>Just as;</p> <pre><code>$scope.image = { logo: 'system/assets/img/logo.png' }; </code></pre> <p>Than the logo is displayed as desired</p>
