Not natively. You’d have to write some code to make it happen – there’s a nice pastebin function that provide the necessary code to do it. Edit (12/19/2011): Yep here’s how you can do this programmatically. Add the following two functions to your functions.php file and you should be good to go. The code has … Read more
When an image size is added either by WordPress(add_image_size), or by a plugin or your own custom code it gets added into the $_wp_additional_image_sizes global, i can’t find a similar function for pulling data from that global, but you could certainly just look inside the global to determine what width and height a registered image … Read more
Related: Filter to remove image dimension attributes? There’s a filter on post_thumbnail_html which receives as its argument the full html element representing the post thumbnail image before it’s echoed to the page. You can filter out the dimensions with a bit of regex: add_filter( ‘post_thumbnail_html’, ‘remove_thumbnail_dimensions’, 10, 3 ); function remove_thumbnail_dimensions( $html, $post_id, $post_image_id ) … Read more
Can’t this simply be done with media_sideload_image() ? Seems pretty simple. Only catch is if you aren’t on admin area, you must include some libraries from within WordPress includes: // only need these if performing outside of admin environment require_once(ABSPATH . ‘wp-admin/includes/media.php’); require_once(ABSPATH . ‘wp-admin/includes/file.php’); require_once(ABSPATH . ‘wp-admin/includes/image.php’); // example image $image=”http://example.com/logo.png”; // magic sideload … Read more
My favorite way of handling this problem has been to use a little documented function I discovered on another stack post: media_sideload_image It works by fetching an image url to the WordPress upload dir and then associating the image to a post’s attachments. You can try it like so: // required libraries for media_sideload_image require_once(ABSPATH … Read more
To built on Max Yudin’s answer you should use the intermediate_image_sizes_advanced filter, and not image_size_names_choose. Add to functions.php function add_image_insert_override($sizes){ unset( $sizes[‘thumbnail’]); unset( $sizes[‘medium’]); unset( $sizes[‘large’]); return $sizes; } add_filter(‘intermediate_image_sizes_advanced’, ‘add_image_insert_override’ ); Another easier option I think works is going to your Settings–>Media and setting each box for width and height to 0
Yep – you can pass the class you want to use to the_post_thumbnail() as part of the attributes argument, for example <?php the_post_thumbnail(‘thumbnail’, array(‘class’ => ‘your-class-name’)); ?> Ref: http://codex.wordpress.org/Function_Reference/the_post_thumbnail#Styling_Post_Thumbnails
I put the following code into my functions.php file. It works! add_filter( ‘wp_image_editors’, ‘change_graphic_lib’ ); function change_graphic_lib($array) { return array( ‘WP_Image_Editor_GD’, ‘WP_Image_Editor_Imagick’ ); } When this helps it is because it changes the PHP code module used for processing the uploaded image for use with WordPress. This processing includes moving the image into the media … Read more
Came here as this post is among the top hits on the search engine when looking for WordPress image alt and title. Being rather surprised that none of the answers seem to provide a simple solution matching the question’s title I’ll drop what I came up with in the end hoping it helps future readers. … Read more
You might also try: If you only have one size thumbnail: $thumbnail = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ) ); Or…if you have multiple sizes: $thumbnail = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), “size” ); Note that wp_get_attachment_image_src() returns an array: url, width, height, is_intermediate. So if you just want only the image url: echo $thumbnail[0]; Resources: http://wpcanyon.com/tipsandtricks/get-the-src-attribute-from-wordpress-post-thumbnail/ https://developer.wordpress.org/reference/functions/wp_get_attachment_image_src/
