Automatically specify image dimensions that are missing width and/or height attributes. Helps with website speed tools.
A simple and lightweight plugin that scans your website and automatically sets the appropriate image dimensions that are missing a width and/or height attributes in your <img> tags.
For example, here are some images with no dimensions set:
<img src="http://link.to/some/img1.jpg" id="123" alt="Some Alt" /> <img class="some-class" src="http://link.to/some/img2.jpg" alt="Another Alt" /> <img class="another-class" src="http://link.to/some/img2.jpg" width="500" />
The plugin will get the actual image dimension and insert the width and height:
<img src="http://link.to/some/img1.jpg" alt="Some Alt" id="123" width="500" height="350" /> <img src="http://link.to/some/img1.jpg" alt="Another Alt" class="some-class" width="500" height="350" /> <img src="http://link.to/some/img1.jpg" class="another-class" width="500" height="350" />
Specifying a width and height for all images allows for faster rendering by eliminating the need for unnecessary re-flows and repaints. This is particularly helpful with website speed tools such as GTmetrix and Google's PageSpeed.
More details from Google
When the browser lays out the page, it needs to be able to flow around replaceable elements such as images. It can begin to render a page even before images are downloaded, provided that it knows the dimensions to wrap non-replaceable elements around. If no dimensions are specified in the containing document, or if the dimensions specified don't match those of the actual images, the browser will require a reflow and repaint once the images are downloaded. To prevent reflows, specify the width and height of all images, either in the HTML
tag, or in CSS.
