    Hi

    I’m using a premium theme that has a function to retrieve a thumbnail image from a post but it doesn’t work if the post is an image attachment type post. Here is the function:

    /* this function gets thumbnail from Post Thumbnail or Custom field or First post image */
if ( ! function_exists( 'get_thumbnail' ) ){
	function get_thumbnail($width=100, $height=100, $class='', $alttext='', $titletext='', $fullpath=false, $custom_field='', $post='')
	{
		if ( $post == '' ) global $post;
		global $shortname;

		$thumb_array['thumb'] = '';
		$thumb_array['use_timthumb'] = true;
		if ($fullpath) $thumb_array['fullpath'] = ''; //full image url for lightbox

		$new_method = true;

		if ( has_post_thumbnail( $post->ID ) && !( '' != $custom_field && get_post_meta( $post->ID, $custom_field, true ) ) ) {
			$thumb_array['use_timthumb'] = false;

			$et_fullpath =  wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' );
			$thumb_array['fullpath'] =  $et_fullpath[0];
			$thumb_array['thumb'] = $thumb_array['fullpath'];
		}

		if ($thumb_array['thumb'] == '') {
			if ($custom_field == '') $thumb_array['thumb'] = esc_attr( get_post_meta($post->ID, 'Thumbnail', $single = true) );
			else {
				$thumb_array['thumb'] = esc_attr( get_post_meta($post->ID, $custom_field, $single = true) );
				if ($thumb_array['thumb'] == '') $thumb_array['thumb'] = esc_attr( get_post_meta($post->ID, 'Thumbnail', $single = true) );
			}

			if (($thumb_array['thumb'] == '') && ((et_get_option($shortname.'_grab_image')) == 'on')) {
				$thumb_array['thumb'] = esc_attr( et_first_image() );
				if ( $fullpath ) $thumb_array['fullpath'] = $thumb_array['thumb'];
			}

			#if custom field used for small pre-cropped image, open Thumbnail custom field image in lightbox
			if ($fullpath) {
				$thumb_array['fullpath'] = $thumb_array['thumb'];
				if ($custom_field == '') $thumb_array['fullpath'] = apply_filters('et_fullpath', et_path_reltoabs(esc_attr($thumb_array['thumb'])));
				elseif ( $custom_field <> '' && get_post_meta($post->ID, 'Thumbnail', $single = true) ) $thumb_array['fullpath'] = apply_filters( 'et_fullpath', et_path_reltoabs(esc_attr(get_post_meta($post->ID, 'Thumbnail', $single = true))) );
			}
		}

		return $thumb_array;
	}
}'

    Can anyone help me modify it to work with an image attachment post?

    Thanks.

    Added this:

    # retrieve image URL from an image attachment post
if (get_post_type( $post->ID ) == 'attachment') {
	$thumb_array['thumb'] = wp_get_attachment_url($post->ID);
	$thumb_array['fullpath'] = $thumb_array['thumb'];
}

    and it works!
