zenphoto press and graphpaper press theme

First, I’m not a programmer, so I’m already in way over my head. Sorry if this appears to be a stupid question.

I’m trying to get things working between my wordpress and zenphoto installs.

I am trying to make use of a graphpaper press theme (F8) which pulls an image from a post and uses that for a thumbnails to display the posts.

It works great if the image is embedded using an <img> tag that points to a particular file, but because I’m using zenphoto and the WP plugin zenphoto press, my <img> aren’t really in the post, they hare there with short code that looks like this:

<img title=”Image Title” src=”https://zenphoto_server.com/zp-core/i.php?a=album&i=imagfilename.jpg&#8221; alt=”Alt Image Text” />

I dug around and I think I found the code in the modularity theme that gets the thumbnail, and it looks like this:

function image_by_scan( $args = array() ) {

/* Search the post’s content for the <img /> tag and get its URL. */
preg_match_all( ‘|<img.*?src=[\'”](.*?)[\'”].*?>|i’, get_post_field( ‘post_content’, $args[‘post_id’] ), $matches );

/* If there is a match for the image, return its URL. */

if ( isset( $matches ) && $matches[1][0] ) {
$scan_finds_image = true;
$matchset = array( ‘url’ => $matches[1][0] );
$matchurl = $matchset[‘url’];
$height = $args[‘height’];
$width = $args[‘width’];
$timthumbprefix = get_bloginfo(‘template_url’).”/includes/timthumb.php?src=”;
$timthumbsuffix = “&h=$height&w=$width&zc=1”;
$timthumbimage = “<img src=’$timthumbprefix$matchurl$timthumbsuffix’ alt=” height=’$height’ width=’$width’ class=’timthumbnail’ />”;
$link_to_post = $args[‘link_to_post’]; if ( $link_to_post ) {
echo ” . $timthumbimage . ”;
} else { echo $timthumbimage; } }
return $scan_finds_image;
}

What I think his happening is that the URL is being built to include a call to more php code, so php code is being sent php code, not a link to an image URL, and the result is that no image is displayed. But being as I’m not a programmer, I don’t know how to alter things so that the image_by_scan function will return a valid img url?
Any ideas?
