Add_image_Size Generator

The Add_image_size function is a built-in WordPress function that allows you to create custom image sizes for your WordPress site. This is useful because it allows you to optimise your images for your site’s design, which can help improve your site’s overall performance. 

By creating custom image sizes, you can ensure that your images are not too large, which can slow down your site’s loading times.

To use the Add_image_size function in WordPress, you need to add a code snippet to your site’s functions.php file. The code snippet should look something like this:

add_image_size( 'custom-size', 220, 180, true );

This code will create a custom image size called ‘custom-size’ with a width of 220 pixels and a height of 180 pixels. The ‘true’ parameter at the end means that WordPress will crop the image to fit these dimensions if necessary.

Yes, you can create multiple custom image sizes with the Add_image_size function. Simply add another code snippet for each custom image size you want to create, with a different name and different dimensions.

Yes, you can use the Add_image_size function to change the default image sizes in WordPress. To do this, you need to add a code snippet to your functions.php file that specifies the new dimensions for the default image sizes. For example, to change the dimensions of the ‘medium’ image size, you would add a code snippet like this:

update_option( 'medium_size_w', 640 );
update_option( 'medium_size_h', 480 );

This code sets the width of the ‘medium’ image size to 640 pixels and the height to 480 pixels.

By creating custom image sizes with the Add_image_size function, you can ensure that your images are optimised for your site’s design and layout. This means that your images will be smaller and more efficiently compressed, which can help improve your site’s overall performance. By reducing the file size of your images, you can also reduce the amount of bandwidth required to load your pages, which can help your site load faster and use less server resources.

Yes, you will need to regenerate your images after using the Add_image_size function to create new custom image sizes. This is because WordPress only generates image sizes on the fly when they are requested by a user’s browser. Regenerating your images will ensure that all of your images are available in the new custom sizes, which will improve your site’s performance and ensure that your images look good across all devices.

Yes, there are several plugins available that can help you use the Add_image_size function in WordPress. Some popular options include Regenerate Thumbnails, Force Regenerate Thumbnails, and Simple Image Sizes. These plugins can help you regenerate your images and manage your custom image sizes more easily, without having to edit any code.
