wp_get_attachment_image_src( int $attachment_id, string|array $size = 'thumbnail', bool $icon = false )
Retrieve an image to represent an attachment.
Description
A mime icon for files, thumbnail or intermediate size for images.
The returned array contains four values: the URL of the attachment image src, the width of the image file, the height of the image file, and a boolean representing whether the returned array describes an intermediate (generated) image size or the original, full-sized upload.
Parameters
- $attachment_id
-
(int) (Required) Image attachment ID.
- $size
-
(string|array) (Optional) Image size. Accepts any valid image size, or an array of width and height values in pixels (in that order).
Default value: 'thumbnail'
- $icon
-
(bool) (Optional) Whether the image should be treated as an icon.
Default value: false
Return
(false|array) Returns an array (url, width, height, is_intermediate), or false, if no image is available.
