Subject: [PATCH] Fix array offset warning in the slider when the image is not
 in the media library

attachment_url_to_postid() returns 0 for a slide image that isn't in the
media library, so wp_get_attachment_image_src() returns false and the
width/height were read from it unguarded. They are now only printed when
the image data exists; the image itself still renders from its URL.

Verified live: a slide with an external image URL logged two "Trying to
access array offset on false" warnings before and none after, and the
image still renders.
