wp_get_attachment_image_src will always return a URL to a file if the image exists in some size. If the size you ask for doesn’t exist then you get the URL for the full size image as uploaded. (This isn’t the “large” image size.) So, for a valid image ID, your conditional if(wp_get_attachment_image_src($id, array($preferred_size, $preferred_size))) will always … Read more
I think the simpler solution would be to create your own function: function get_theme_mod_img($mod_name){ return str_replace(array(‘http:’, ‘https:’), ”, get_theme_mod($mod_name)); } then just use it: <a href=”https://wordpress.stackexchange.com/questions/256864/<?php echo esc_url(get_theme_mod(“slide_one_link’)); ?>”><img src=”<?php echo esc_url( get_theme_mod_img( ‘slide_img_upload_one’ ) ); ?>” alt=”<?php echo get_theme_mod( ‘slide_title_1’ ); ?>” /></a> there is another solution that involve filters as you can see … Read more
Despite having no plugins installed through wordpress, I did have retina.min.js being enqueued in my functions.php file from the template I downloaded. Retina.min.js (source: http://imulus.github.io/retinajs/) looks for high resolution versions (denoted with suffix @2x right before the extension) of each image in your site and attempts to replace them if any are found. Since I … Read more
OK I seem to have found the answer to this. The theme I’m using has Aqua Resizer installed. Quality was set to 100% which for some reason made the resized versions bigger in file size. I’ve changed the quality setting to 80 and it has sorted it.
I can’t say I’ve tested this but here’s what you could to, it should in theory work. The wp_get_attachment_image() functions 4th parameter is an array of attributes. You should be able to pass what you get returned from wp_get_attachment_image_srcset() to the attribute parameter as follows, sort of similar to the example seen on the docs. … Read more
I’ve modified method wp_update_attachment_metadata from wp-includes/post.php (line 5070) to this, just during the Import: /** * Update metadata for an attachment. * * @since 2.1.0 * * @param int $attachment_id Attachment post ID. * @param array $data Attachment meta data. * @return int|bool False if $post is invalid. */ function wp_update_attachment_metadata( $attachment_id, $data ) { … Read more
Running the wp media regenerate command from WP-CLI with the –only-missing argument is quite fast (takes about 30 seconds for 4000 images) and rebuilds _wp_attachment_metadata correctly: wp media regenerate –only-missing
How to disable this behaviour? Add this to your functions.php: add_filter( ‘big_image_size_threshold’, ‘__return_false’ ); How does it work? When a new image is uploaded, WordPress will detect if it is a “big” image by checking if its height or width exceeds the big_image threshold. The default threshold value is 2560px, filterable with the new big_image_size_threshold … Read more
This can be done using block filters. First, you’ll need to filter block attributes for the image block to be able to save the new items: const { addFilter } = wp.hooks; function filterAttributes( settings, name ) { if ( ‘core/image’ === name && settings.attributes ) { settings.attributes.description = { type: ‘string’, default: ” }; … Read more
