Conditional Tag for Attachment

anyone?

With this search:
https://www.google.com/search?q=wordpress+how+see+if+post+has+thumbnail+image

found this forum thread:

So used that for this.

<?php
$images =get_children( 'post_type=attachment&post_mime_type=image&post_parent=' . $post->ID );
if ($images) {
foreach( $images as $imageID => $imagePost ) {
$thumb_url = wp_get_attachment_thumb_url($imageID);
if ($thumb_url ) {
echo 'here is the thumbfile url ' . $thumb_url;
//**just in case echo wp_get_attachment_image($imageID, 'thumbnail', false);
}
}
}
?>
