A lot of the time the reason it isn’t working because you haven’t regenerated the thumbnails for all your images. If you have changed the dimensions of your images you will need to regenerate your thumbnails using this plugin: http://wordpress.org/extend/plugins/regenerate-thumbnails/
if you are referring to the ‘page for posts’, then try (only relevant section of your code shown): if (is_home() && get_option(‘page_for_posts’) ) { $img = wp_get_attachment_image_src(get_post_thumbnail_id(get_option(‘page_for_posts’)),’full’); $featured_image = $img[0]; } else {
$Featured_image = $wpdb->get_results(” SELECT p.* FROM net_5_postmeta AS pm INNER JOIN net_5_posts AS p ON pm.meta_value=p.ID WHERE pm.post_id = $da_id AND pm.meta_key = ‘_thumbnail_id’ ORDER BY p.post_date DESC LIMIT 15 “,’ARRAY_A’);
It is necessary to set an alt value for all of your images, in case a browser can not load the image or the visitor is using screen reader. You have two options. Either use the featured image’s caption (which can some times be blank) or use the post’s title as alt. You can get … Read more
Seems that the answer is no… I’ve followed the core functions and found a dead-end. And found this post ( How can I make add_image_size() crop from the top? ) where Rarst says: Intermediate image generation is extremely rigid. Image_resize() keeps it close to code and completely lacks hooks. But, following the lead of the … Read more
There’s not enough info to be sure this answer is definitive but here’s an attempt. Firstly make sure the image you are uploading is actually larger than the size you have defined. I see people upload images that are too small and then get this sort of result all the time. Secondly, WP will only … Read more
add_filter( ‘wp_generate_attachment_metadata’, ‘delete_fullsize_image’ ); function delete_fullsize_image( $metadata ) { $upload_dir = wp_upload_dir(); $full_image_path = trailingslashit( $upload_dir[‘basedir’] ) . $metadata[‘file’]; $deleted = unlink( $full_image_path ); return $metadata; }
Assuming the question is about wp_get_attachment_image_src. It could be also about wp_get_attachment_link, but, although related, this analysis doesn’t includes it. Got aware of this issue answering this question: How can I view all WP generated thumbnails in Media Manager?. Refer to it to see a working code regarding the issue on this Question. And it … Read more
i have only had to do this on a couple of occasions, but each time i have used this regenerate thumbnails plugin on each occasion with a 100% success rate, however (as you will expect it did take quite a bit of time as i had over a 1000 images that it had to wade … Read more
You could do it by adding an action to the hook ‘rss2_item’ like so: add_action(‘rss2_item’, function(){ global $post; $output=””; $thumbnail_ID = get_post_thumbnail_id( $post->ID ); $thumbnail = wp_get_attachment_image_src($thumbnail_ID, ‘thumbnail’); $output .= ‘<post-thumbnail>’; $output .= ‘<url>’. $thumbnail[0] .'</url>’; $output .= ‘<width>’. $thumbnail[1] .'</width>’; $output .= ‘<height>’. $thumbnail[2] .'</height>’; $output .= ‘</post-thumbnail>’; echo $output; });
