It’s the image_send_to_editor filter: if(is_admin()){ add_filter(‘image_send_to_editor’, ‘wrap_my_div’, 10, 8); function wrap_my_div($html, $id, $caption, $title, $align, $url, $size, $alt){ return ‘<div class=”mydiv” id=”mydiv-‘.$id.'”>’.$html.'</div>’; } } For existing images/posts you can try the regex in the function below

(Update 04.05.2012: Include captions) Let’s start with a solution … There is no filter especially for gallery image links. There is also no filter for the gallery shortcode output. So we have to fake one: add_action( ‘after_setup_theme’, ‘wpse_50911_replace_img_shortcodes’ ); /** * Replace the default shortcode handlers. * * @return void */ function wpse_50911_replace_img_shortcodes() { remove_shortcode( … Read more
I won’t go into the code specifics right now, because I am not sure if you need me to. You essentially need to modify the SWFUpload JavaScript settings array to set the file_upload_limit to 1. Unfortunately I don’t believe SWFUpload allows you to change that settings variable after it has been inited, because it has … Read more
Instead of pasting into the Visual editor, switch to the html editor for pasting any kind of html, or using shortcodes. I’d recommend checking the “disable the visual editor” checkbox in your user profile. Then install Mark Jaquith’s Markdown on Save plugin for more readable formatting without the wysiwyg pitfalls.

You’re going to hook into wp_enqueue_script, and call wp_enqueue_script to add your gallery script to the … Read more
I think I’ve answered my own question sort of…. As I was using a child theme of Hybrid I activated the cleaner gallery extension in the functions.php file: add_theme_support( ‘cleaner-gallery’ ); Then, based on the topic here I created my own filter: add_filter( ‘cleaner_gallery_image’, ‘my_gallery_image’, 10, 4 ); function my_gallery_image( $image, $id, $attr, $instance ) … Read more
I’ve found a solution : // Remove <img> title attribute in // http://wordpress.org/support/topic/wp_get_attachment_image_attributes-filter-not-working function remove_img_title($atts) { unset($atts[‘title’]); return $atts; } add_filter(‘wp_get_attachment_image_attributes’,’remove_img_title’, 10, 4); // remove title attribute from <a> title attribute in // modified from this post : http://oikos.org.uk/2011/09/tech-notes-using-resized-images-in-wordpress-galleries-and-lightboxes/ function ah_get_attachment_link_filter( $content ) { $new_content = preg_replace(‘/title=\'(.*?)\”https://wordpress.stackexchange.com/”, ”, $content ); return $new_content; } add_filter(‘wp_get_attachment_link’, ‘ah_get_attachment_link_filter’, … Read more
How about PHP Function getimagesize() <? $sImageurl = of_get_option(‘slideshow_1’); list($iWidthinpx, $iHeightinpx) = getimagesize($sImageurl); echo ‘<img src=”‘ . $sImageurl . ‘” width=”‘ . $iWidthinpx. ‘” height=”‘ . $iHeightinpx. ‘” alt=”#”/>’; ?> or if you know the attachment id instead of the attachment url you could use <? $aImagedata = wp_get_attachment_image_src($iAttachmentid, ‘my-image-size’, false); list($sImageurl, $iWidthinpx, $iHeightinpx) = … Read more
The image attachment type is stored in the postmeta table in the _wp_attachment_metadata meta key. The data is serialized, so it can’t be filtered on. But you could use a meta_query in your query: $images = get_posts( array( ‘post_type’ => ‘attachment’, ‘orderby’ => ‘rand’, ‘posts_per_page’ => -1, ‘meta_query’ => array( array( ‘key’ => ‘_wp_attachment_metadata’, ‘value’ … Read more
