[Plugin: Multiple Post Thumbnails] A feature suggestion

Hi,

Just a feature suggestion..

When the preview is rendered it tries to pick a custom thumbnail size "{$this->post_type}-{$this->id}-thumbnail" then default to a hard coded value.

I think it would make sense to fall back to the default post behaviour between the two case scenario and pick post-thumbnail if the first one isn’t available.

Something like this works for me:

if ( isset($_wp_additional_image_sizes["{$this->post_type}-{$this->id}-thumbnail"]))
	$thumbnail_html = wp_get_attachment_image($thumbnail_id, "{$this->post_type}-{$this->id}-thumbnail");
elseif ( isset($_wp_additional_image_sizes["post-thumbnail"]))
	$thumbnail_html = wp_get_attachment_image($thumbnail_id, "post-thumbnail");
else
	$thumbnail_html = wp_get_attachment_image($thumbnail_id, array($content_width, $content_width));
