Specify image dimensions
I ran a performance report for my website (using GTmetrix) and I realized the image dimensions are not set, and I missed specifying the height and width attributes. The theme already had some images, but they are not specified by default. How can I specify them and more importantly, where do I specify the attributes height and width?
<div class="thumb"> <a class="clip-link" data-id="1" title="Hello world!" href="http://example.com/hello-world/"> <span class="clip"> <img src="http://example.com/wp-content/themes/beetube/images/nothumb.png" alt="Hello world!" /> <span class="vertical-align"></span> </span>
