Get the bare URL for an attachment

Question

I'm trying to get the link to the thumbnail size of an attachment image.

I tried this:

wp_get_attachment_link( $img_id, 'thumbnail' );

but it returns the actual HTML for the image wrapped in a link. I want just the bare URL directly to that size image.

Does Wordpress have a different function I should be using, or do I have to extract it from the HTML returned by wp_get_attachment_link?

Answer 1

What about using wp_get_attachment_image_src?

Using wp_get_attachment_image_src:

$src = wp_get_attachment_image_src( $img_id, 'thumbnail' );
$src = $src[0]; // Grabs only the URL ($src[1] = width of image, $src[2] = height of image)
