    Very nice plugi, i am really finding it useful. Just one minor question.

    I am using lightbox to enlarge the images on posts and main page. I have the images showing correctly (thumbnail), but how to i allow them to be dealt with by lightbox ? Essentially I am trying add rel=lightbox" to user submitted images.

    So far i have made changes to template_tags.php:

    $href = '<a href="';
    $hrefend = '">';
    $aend = '</a>';
    echo $href . $info[0] . $hrefend . $beforeUrl . $info[0] . $afterUrl . $aend;

    The issue now is selecting a thumbnail for initial and medium or large for the enlarge.

    Is there a way i can specify from here if i want a thumbnail or large instead of the one in the actual page being the reference?

    What i am thinking is something like:
    $info[0]->large and $info[0]->thumbnail

    Another potential is :

    $info = wp_get_attachment_image_src($attachment->ID, $size);
     $info2 = wp_get_attachment_image_src($attachment->ID, large);
    echo $href . $info2[0] . $hrefend . $beforeUrl . $info[0] . $afterUrl . $aend;

    This works, but then i get errors when uploading the image. I cant get pas this bit.

    First of all this is a damn great plugin! Great work and keep it up!

    Just to clarify, as I think this post was resolved but the solution not clear to everybody. I modified the template-tags.php file located in the library directory of the user-submitted-posts plugin directly.

    The following works perfectly, with one or multiple images to display in a "slideshow" using WP Lightbox 2 (another great plugin). Here are the changes (included between FIX and EOF, basically a miserable one line addition + a change in the returned string of the echo call:

    function usp_post_attachments($size = 'full', $beforeUrl = '<img src="', $afterUrl = '" />', $numberImages = false, $postId = false) {
    	if (false === $postId) {
    		global $post;
    		$postId = $post->ID;
    	/*if (!in_array($size, array('thumbnail', 'medium', 'large', 'full'))) {
    		$size = 'full';
    	if (false === $numberImages || !is_numeric($numberImages)) {
    		$numberImages = 99;
    	$attachments = get_posts(array('post_type'=>'attachment', 'post_parent'=>$postId, 'post_status'=>'inherit', 'numberposts'=>$numberImages));
    	foreach ($attachments as $attachment) {
    // FIX for supporting LightBox with WP-LightBox 2
    		$info = wp_get_attachment_image_src($attachment->ID, $size);
    		$lightBoxedUrl = wp_get_attachment_image_src($attachment->ID, 'large');
    		echo '<a href="' . $lightBoxedUrl[0] . '" rel="lightbox[uspgallery]">' . $beforeUrl . $info[0] . $afterUrl . '</a>';
    // EOF

    I don't like to modify plugins code directly, for obvious plugins upgrade reasons, therefore, a "clean" way, more painful though would be to actually create a function in your theme to deal with this, but for the purpose of the site I am working on, it's far enough and works as expected 100%.

    Jeff, I suggest you an option for lightbox support to usp_post_attachments() given lightbox is widely used everywhere.

    Keep the good work up!

    Thanks RaPhiuS! I'm looking at adding lightbox support in the upcoming Pro version of User Submitted Posts. Thanks for the suggestion!
