Custom Image Search/Search Results hangs

I recently hired a programmer to write some custom code for me so that my WP has a Image and Category search and search results pages. After some back and forth and issues he finally got it working….. for about a day. Now when I enter a keyword or use the category pull down it just hangs and hangs….. and finally where the thumbnails on the results page should show up I get an error message that says…..

Warning: getimagesize(https://www.zenstream.net/zenphotos/thumbs/bal1-050.jpg) [function.getimagesize]: failed to open stream: No route to host in /hermes/bosweb/web212/b2124/nf.zenstreaminfo

…..so I checked the [function.getimagesize] to see if there was some clues to the problem but I am useless at php thats why I hired the programmer.

this is the function.getimagesize code fro the functions.php page

function getImage($num) {
	global $more;
	$more = 1;
	$link = get_permalink();
	$content = get_the_content();
	$count = substr_count($content, '<img');
	$start = 0;
	for($i=1;$i<=$count;$i++) {
		$imgBeg = strpos($content, '<img', $start);
		$post = substr($content, $imgBeg);
		$imgEnd = strpos($post, '>');
		$postOutput = substr($post, 0, $imgEnd+1);
		//$postOutput = preg_replace('/width="([0-9]*)" height="([0-9]*)"/', '',$postOutput);
		$postOutput = preg_replace('/alt="/', '/width="180" class="attachment-180x180" alt="',$postOutput);
		$image[$i] = $postOutput;
		$start=$imgEnd+1;
	}
	if(stristr($image[$num],'<img')) { echo '<a href="'.$link.'">'.$image[$num]."</a>"; }
	$more = 0;
}

function getThumb($num) {
	global $more;
	$more = 1;
	$imgwidth = "";
	$imgclass = "";
	$link = get_permalink();
	$content = get_the_content();
	$count = substr_count($content, '<img');
	$start = 0;
	for($i=1;$i<=$count;$i++) {
		$imgBeg = strpos($content, '<img', $start);
		$post = substr($content, $imgBeg);
		$imgEnd = strpos($post, '>');
		$postOutput = substr($post, 0, $imgEnd+1);
		$srcBeg = strpos($postOutput, 'src=');
		$source = substr($postOutput, $srcBeg+5);
		$srcEnd = strpos($source, '"');
		$sourceOutput = substr($source, 0, $srcEnd);
		$sourceOutput = preg_replace('/lowresWM/', 'thumbs', $sourceOutput);
		$image[$i] = $sourceOutput;
		$start=$imgEnd+1;
	}

..any suggestions would be seriously appreciated. or at least some direction on how to narrow down the problem.

The URL is:
https://www.zenstream.net/zen/
if anyone wants to test use the keyword “bali” or the category pull down “bali”. the others just come up as no search results.

Thank You.
