Image Galleries Theming

Hello Staff,

I am stating change the view that the Image Gallery (image of the module) is standard. The next part of the code that makes the current view:

if (!empty($images)) {
        $content .= '<ul class="images">';
                foreach ($images as $image) {
                $content .= theme('image_gallery_img', $image, $size);
        }
        $content .= "</ul>\n";
}
 
function theme_image_gallery_img($image, $size) {
        $width = $size['width'];
        // We'll add height to keep thumbnails lined up.
        $height = $size['height'] + 75;
       
        $content = '<li';
        if ($image->sticky) {
                $content .= ' class="sticky"';
        }
        $content .= " style='height : {$height}px; width : {$width}px;'>\n";
        $content .= l(image_display($image, IMAGE_THUMBNAIL), 'node/'. $image->nid, array(), NULL, NULL, FALSE, TRUE);
        $content .= '<h3>'. l($image->title, 'node/'. $image->nid) .'</h3>';
        if (variable_get('image_gallery_node_info', 0)) {
                $content .= '<div class="author">'. t('Posted by: !name', array('!name' => theme('username', $image))) ."</div>\n";
                if ($image->created > 0) {
                        $content .= '<div class="date">'. format_date($image->created) ."</div>\n";
                }
        }
        $content .= "</li>\n";
        return $content;
}

The result of that code looks like this:

<ul class="images">
    <li style='height : 150px; width : 100px;'>
        <a href="/gallery/?q=node/4"><img src="http://localhost/gallery/files/images/Dia-dos-pais-2008-008.thumbnail.jpg" alt="Peixinho e Cavalinho 2" title="Peixinho e Cavalinho 2"  class="image image-thumbnail " width="100" height="75" /></a>
        <h3><a href="/frog-gallery/?q=node/4">Peixinho e Cavalinho 2</a></h3></li>
    <li style='height : 150px; width : 100px;'>
</ul>

I need that the display is also this:

<div id="gallery">
        <a href="images/1.jpg">
                <img src="images/1_thumb.jpg" />
        </a>
</div>

I tried to use the Content Template but forgot it only serves to Contant Types. Do you have any idea how can I change this?

Thank you again.
