Responsive WordPress images are taking the world by storm, and it's impossible to overlook their growing popularity. But here's the thing: implementing this functionality in widely used CMS platforms like WordPress can be quite the challenge. It's a time-consuming task, even though users can include features within the theme. So, buckle up and get ready to dive into the exciting world of WordPress responsive images! 

Ever since WordPress 4.4 was introduced, developers and administrators can embed responsive image functionality into their themes. The major highlight includes the availability of the Responsive Images plug-in within WordPress core . Users can now enjoy responsive image support, a default WordPress feature

Let’s closely examine how this feature works and how it can be used carefully to harness the WordPress site's potential.

Functioning of the Feature

All content and images will comprise srcset and size attributes. This is mainly to ensure the availability of every image size. If the aspect ratio varies, the custom crops will be left out of the srcset attribute. Responsive images would be returned when an image is called through the wp-getattachment-image function.

Enhanced backgrounds & borders

Responsive images are a background feature in WordPress 4.4 due to their automatic functionality upon image upload. This automatic process displays srcset and size attributes whenever an image is utilized on a page. Consequently, the new responsive images feature lacks visible interfaces, such as forms for filling, checkboxes for selection, and toggling options.

For WordPress theme developers, it is imperative to ensure the provision of accurate sizes attributes in images through editing the theme's functions.php file. It is essential to consider it because the srcset and size attributes in the image tag represent the responsive images in WordPress. Although sizes in the srcset attribute are available, the sizes attribute remains challenging to predict. Improving the writing quality, optimizing word choice, sentence structure, readability, and eloquence while retaining the original meaning. It is the duty of the sizes attribute to explain to n the browser how wide the image would be at every available viewport. However, the results can differ depending on styling available with the user’s theme, providing the reasonable default, namely ‘sizes=” (max-width: {{image-width}}) 100 vw, {{image-width}}”

Media Settings

With the sizes attribute, users can accomplish especially two things. Firstly, they can ensure the availability of a valid size attribute in the image, which has now become a prerequisite for the specifications. Secondly, they can prevent the browser from providing an image source that is more compared to the original width that has been requested. However, the default sizes attribute's benefit becomes less whenever any CSS manipulates the image size at viewport widths that are entirely different.

Theme developers can adjust the sizes attribute for each image using filter hooks. This ensures that perfect size attributes are delivered for every breakpoint. It's desirable for a theme to offer accurate and responsive image support without relying on the default sizes attribute. 

Action Hook

The main reason for this is that browsers cannot modify the image source when the viewport size is smaller than the original requested image size. However, the source cannot be changed if the image has been altered with CSS at a breakpoint.

Suppose you have access to a WordPress Code Base or a theme developer. In that case, it is more necessary to filter the images in the themes to deliver accurate size attributes. It is the most important thing to be done after the new version is released.
