You appear to be a bot. Output may be restricted

Description

Gets the "thumbnail" image for an attachment

This no longer sets the width and height of the image. Does this work when we want a really small image?

Usage

$string = bw_get_attachment_thumbnail( $post_id, $size, $atts );

Parameters

$post_id

( int ) required – ID of the attachment

$size

( mixed ) required – size of the required image

$atts

( array ) required – contains the title for the attachment

Returns

string $thumbnail – either an image or just the attachment file name
