| wp_get_additional_image_sizes() X-Ref |
| Retrieve additional image sizes. return: array Additional images size data. since: 4.7.0 |
| image_constrain_size_for_editor( $width, $height, $size = 'medium', $context = null ) X-Ref |
| Scale down the default size of an image. This is so that the image is a better fit for the editor and theme. The `$size` parameter accepts either an array or a string. The supported string values are 'thumb' or 'thumbnail' for the given thumbnail size or defaults at 128 width and 96 height in pixels. Also supported for the string value is 'medium', 'medium_large' and 'full'. The 'full' isn't actually supported, but any value other than the supported will result in the content_width size or 500 if that is not set. Finally, there is a filter named {@see 'editor_max_image_size'}, that will be called on the calculated array for width and height, respectively. return: int[] { param: int $width Width of the image in pixels. param: int $height Height of the image in pixels. param: string|int[] $size Optional. Image size. Accepts any registered image size name, or an array param: string $context Optional. Could be 'display' (like in a theme) or 'edit' since: 2.5.0 |
| image_hwstring( $width, $height ) X-Ref |
| Retrieve width and height attributes using given width and height values. Both attributes are required in the sense that both parameters must have a value, but are optional in that if you set them to false or null, then they will not be added to the returned string. You can set the value using a string, but it will only take numeric values. If you wish to put 'px' after the numbers, then it will be stripped out of the return. return: string HTML attributes for width and, or height. param: int|string $width Image width in pixels. param: int|string $height Image height in pixels. since: 2.5.0 |
| image_downsize( $id, $size = 'medium' ) X-Ref |
| Scale an image to fit a particular size (such as 'thumb' or 'medium'). The URL might be the original image, or it might be a resized version. This function won't create a new resized copy, it will just return an already resized one if it exists. A plugin may use the {@see 'image_downsize'} filter to hook into and offer image resizing services for images. The hook must return an array with the same elements that are normally returned from the function. return: array|false { param: int $id Attachment ID for image. param: string|int[] $size Optional. Image size. Accepts any registered image size name, or an array since: 2.5.0 |

| Gets an img tag for an image attachment, scaling it down if requested. The {@see 'get_image_tag_class'} filter allows for changing the class name for the image without having to use regular expressions on the HTML content. The parameters are: what WordPress will use for the class, the Attachment ID, image align value, and the size the image should be. The second filter, {@see 'get_image_tag'}, has the HTML content, which can then be further manipulated by a plugin to change all attribute values and even HTML content. return: string HTML IMG element for given image attachment param: int $id Attachment ID. param: string $alt Image description for the alt attribute. param: string $title Image description for the title attribute. param: string $align Part of the class name for aligning the image. param: string|int[] $size Optional.

Cropping behavior is dependent on the value of $crop: 1. If false (default), images will not be cropped. 2. If an array in the form of array( x_crop_position, y_crop_position ): - x_crop_position accepts 'left' 'center', or 'right'. - y_crop_position accepts 'top', 'center', or 'bottom'. Images will be cropped to the specified dimensions within the defined crop area. 3. If true, images will be cropped to the specified dimensions using center positions. return: array|false Returned array matches parameters for `imagecopyresampled()`. False on failure. param: int $orig_w Original width in pixels. param: int $orig_h Original height in pixels. param: int $dest_w New width in pixels. param: int $dest_h New height in pixels. param: bool|array $crop Optional.

| image_get_intermediate_size( $post_id, $size = 'thumbnail' ) X-Ref |
| Retrieves the image's intermediate size (resized) path, width, and height. The $size parameter can be an array with the width and height respectively. If the size matches the 'sizes' metadata array for width and height, then it will be used. If there is no direct match, then the nearest image size larger than the specified size will be used. If nothing is found, then the function will break out and return false. The metadata 'sizes' is used for compatible sizes that can be used for the parameter $size value. The url path will be given, when the $size parameter is a string. If you are passing an array for the $size, you should consider using add_image_size() so that a cropped version is generated. It's much more efficient than having to find the closest-sized image and then having the browser scale down the image. return: array|false { param: int $post_id Attachment ID. param: string|int[] $size Optional.

| wp_get_attachment_image( $attachment_id, $size = 'thumbnail', $icon = false, $attr = '' ) X-Ref |
| Get an HTML img element representing an image attachment. While `$size` will accept an array, it is better to register a size with add_image_size() so that a cropped version is generated.

| _wp_add_additional_image_sizes() X-Ref |
| Add additional default image sub-sizes. These sizes are meant to enhance the way WordPress displays images on the front-end on larger, high-density devices. They make it possible to generate more suitable `srcset` and `sizes` attributes when the users upload large images. The sizes can be changed or removed by themes and plugins but that is not recommended. The size "names" reflect the image dimensions, so changing the sizes would be quite misleading. since: 5.3.0 |

| wp_get_loading_attr_default( $context ) X-Ref |
| Gets the default value to use for a `loading` attribute on an element. This function should only be called for a tag and context if lazy-loading is generally enabled. The function usually returns 'lazy', but uses certain heuristics to guess whether the current element is likely to appear above the fold, in which case it returns a boolean `false`, which will lead to the `loading` attribute being omitted on the element. The purpose of this refinement is to avoid lazy-loading elements that are within the initial viewport, which can have a negative performance impact. Under the hood, the function uses {@see wp_increase_content_media_count()} every time it is called for an element within the main content. If the element is the very first content element, the `loading` attribute will be omitted. This default threshold of 1 content element to omit the `loading` attribute for can be customized using the {@see 'wp_omit_loading_attr_threshold'} filter. return: string|bool The default `loading` attribute value. Either 'lazy', 'eager', or a boolean `false`, to indicate param: string $context Context for the element for which the `loading` attribute value is requested. since: 5.9.0 |
| wp_omit_loading_attr_threshold( $force = false ) X-Ref |
| Gets the threshold for how many of the first content media elements to not lazy-load. This function runs the {@see 'wp_omit_loading_attr_threshold'} filter, which uses a default threshold value of 1. The filter is only run once per page load, unless the `$force` parameter is used. return: int The number of content media elements to not lazy-load. param: bool $force Optional. If set to true, the filter will be (re-)applied even if it already has been before. since: 5.9.0 |
| wp_increase_content_media_count( $amount = 1 ) X-Ref |
| Increases an internal content media count variable. return: int The latest content media count, after the increase. param: int $amount Optional. Amount to increase by. Default 1. since: 5.9.0 |
