It appears the problem was that image size variants were being capped by the max_srcset_image_width property that can be raised with the following: add_filter( ‘max_srcset_image_width’, ‘setSrcsetMaximumWidth’, 10, 2 ); function setSrcsetMaximumWidth( $max_srcset_image_width, $sizes_array ) { return 3200; } I was never aware of this before and have no idea why I never ran into this.
To set a featured image when creating a post using wp_insert_post(), you can use the set_post_thumbnail() function // Create the post $post_id = wp_insert_post($args); // Check if the post was created successfully if (!is_wp_error($post_id)) { // Set the featured image if ($image_url) { // $image_url should be the URL of the image you want to … Read more
Those are attachments, all items in the media library are represented as posts of type attachment in the database, that’s how WordPress knows which images/media you have and how it displays them. The media library isn’t a file/folder viewer, and this is why copying an uploads folder or putting files in there manually won’t fill … Read more
In the place where you use get_the_title($post_id) you need to get the alt attribute that is stored in the post metadata like this: esc_attr (get_post_meta ($post_id, ‘_wp_attachment_image_alt’, true))
you are trying to get the image title using get_the_title($image_id), but $image_id is not defined in your function. Instead, you should use the id attribute provided in the shortcode attributes. add_filter( ‘img_caption_shortcode’, ‘my_img_caption_shortcode’, 10, 3 ); function my_img_caption_shortcode( $output, $attr, $content ) { $attr = shortcode_atts( array( ‘id’ => ”, ‘align’ => ‘alignnone’, ‘width’ => … Read more

Call get_intermediate_image_sizes() before applying the filter (intermediate_image_sizes). Or, temporarily remove the filter, call the function to store the output, and then re-apply the filter. If you only want the list of default image sizes, then you can remove the values returned by wp_get_additional_image_sizes() from those returned by get_intermediate_image_sizes() (untested): remove_filter( ‘intermediate_image_sizes’, … ); $image_sizes = … Read more
It seems that this regex does the trick: wp search-replace ‘(<!– wp:image\s{(?!.*”sizeSlug”)[^}]*)’ ‘$1,\”sizeSlug\”:\”full\”‘ wp_posts –regex –regex-delimiter=”https://wordpress.stackexchange.com/” –precise EDIT: I added correction, double quotes must be escaped in replacement string in order for this to work properly. It seems that everything is first encoded in json, hence the reason. ANOTHER EDIT: This did the trick by … Read more
Try using JavaScript to handle this situation. The script should run when a user attempts to upload an image, and if the image upload fails, it will remove the associated UI elements (including that stubborn loading bar). Here’s a quick code: jQuery(document).ready(function($) { wp.Uploader.prototype.init = function() { this.uploader.bind(‘BeforeUpload’, function(uploader, file) { uploader.settings.multipart_params = { …uploader.settings.multipart_params, … Read more
