Can I grab the URL link from an uploaded image?

    The idea is one big box that contains a thumbnail image and title. Click anywhere on the big box and off you go. ie click the image, text or background.

    Can I grab the external URL from the uploaded image? I want to make it dead simple for the authors to input that URL. I was thinking they could upload an image and input the external URL into the “link URL” when they upload the image. If I was then able to grab that I could use that as my box and text url.

    I think the code goes something like this:

    <?php
query_posts('category_name=press');

global $more;
// set $more to 0 in order to only get the first part of the post
$more = 0; 

// the Loop
while (have_posts()) : the_post();
?>
<div id="pressEntry">
<a href="#"><!-- How do I get the link? Can it be taken from the image information -->
<div id="title"><?php the_title(); ?></br></a></div>
<?php the_content(''); ?>
</a>
</div><!-- close press entry -->

<?php
endwhile;
?>

    While reading up on custom fields I accidentally came across the answer to my problem. The solution is to create a custom field called “externalURL” and adding an if statement to my loop. If “externalURL” exists; show the post with a link to that URL Else run the usual post.

    Here is the script:

    <div class="press">

					<!--check to see if this is an external link -->
						<?php
						$key = 'externalURL';
						$themeta = get_post_meta($post->ID, $key, TRUE);

						if($themeta != '') {
						echo 'this is an external link';
						?>
						<a href="<?php echo get_post_meta($post->ID, 'externalURL', true); ?>" title="<?php the_title(); ?>">
						<div id="title"><?php the_title(); ?></div>
						<?php the_content(''); ?></br>
						<div id="publishDate"><?php the_time('M Y'); ?></div>	

						</a>

<?php
						}
					else{
?>
						<a href="<?php the_permalink(); ?>">
						<div id="title"><?php the_title(); ?></div>
						<?php the_content(''); ?></br>
						<div id="publishDate"><?php the_time('M Y'); ?></div>
						</a>
						<?php
						}
						?>

</div>
