Gets an img tag for an image attachment, scaling it down if requested.
Syntax Syntax
Description Description
The ‘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, ‘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.
Parameters Parameters
- $id
-
(Required) Attachment ID.
- $alt
-

- $title

- $align

- $size
-
(Optional) Registered image size to retrieve a tag for. Accepts any valid image size, or an array of width and height values in pixels (in that order). Default 'medium'.
Default value: 'medium'
Return Return
(string) HTML IMG element for given image attachment
