The best way to assign images to a given post is to just upload them in the WordPress post editing/new post area. You can also delete images from there. With that said, here would be how you do that. You’re going to hook into wp_enqueue_script, and call wp_enqueue_script to add your gallery script to the … 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
I think it is a better idea, if you filter the output, the the_content and add the div on all images. It is better for feature, if you will remove this markup, it is not inside the database. add_filter( ‘the_content’, ‘fb_add_div_to_img’ ); function ( $content ) { // find img and add markup return $content; … Read more

add_image_size does change the actual size of the image file. What I hava tried: function odevice_image_sizes() { add_image_size( ‘iphone-size’, 300, 100, true );//OF course the dimensions are not correct… add_image_size( ‘tablet-size’, 600, 300, true ); } function show_odevice_at_img_select($sizes) { $sizes[‘iphone-size’] = __( ‘Image size for iphone’ ); $sizes[‘tablet-size’] = __( ‘image size for tablet’ ); … Read more
I wonder if this will work for you: add_action( ‘add_attachment’, function( $attachment_id ){ $a = get_post( $attachment_id ); if ( is_object( $a ) && ‘image’ === substr( $a->post_mime_type, 0, 5 ) ) wp_insert_attachment( array( ‘ID’ => $a->ID, ‘post_excerpt’ => $a->post_content ) ); }); or with less queries: add_action( ‘add_attachment’, function( $attachment_id ){ global $wpdb; if( … Read more
The header image is already set to 100% width by default. Check lines 571-578 in style.css of the twenty fourteen theme #site-header img { max-width: 100%; } If you need a bigger header, you’ll need to set the sizes accordingly in the code in your question, which I suppose you got from one of my … Read more
why didn’t use add_image_size( ‘horizontal_img’, 800, 300, true ); add_image_size( ‘vertical_img’, 300, 800, true ); And then $image_hor = wp_get_attachment_image_src($post_id,’horizontal_img’); $image_ver = wp_get_attachment_image_src($post_id,’vertical_img’); when echo $image_hor[0] you will get your desire sized image url. Thanks Musa
There are multiple solutions: Use CSS for post images: .post img { height: 300px; width: auto; } Use a custom thumbnail size. Either in Settings -> Media or use a third-party plugin to generate them. Another way would be to code your own: function custom_image_sizes() { add_theme_support(‘post-thumbnails’); add_image_size(‘breaking-news’, 9999, 300, true); } function add_custom_sizes( $imageSizes … Read more
