The Approach I think the best approach is to create an image size “on the fly”, just before the images is resized. You can do that using ‘intermediate_image_sizes_advanced’ filter hook. That allows you to edit the size to be generated, but being aware of the current image size, that is stored in the array $metadata … Read more
I recently had to do this via a nightly cron script for a social media stream. $parent_id is the ID of the post you want to attach the image to. function uploadRemoteImageAndAttach($image_url, $parent_id){ $image = $image_url; $get = wp_remote_get( $image ); $type = wp_remote_retrieve_header( $get, ‘content-type’ ); if (!$type) return false; $mirror = wp_upload_bits( basename( … Read more
I found the culprit! WordPress 5.3 introduced additional image sizes which can be found via /wp-includes/media.php. Updating my function, like so, removed the extra sizes: function remove_default_image_sizes( $sizes) { unset( $sizes[‘large’]); // Added to remove 1024 unset( $sizes[‘thumbnail’]); unset( $sizes[‘medium’]); unset( $sizes[‘medium_large’]); unset( $sizes[‘1536×1536’]); unset( $sizes[‘2048×2048’]); return $sizes; } add_filter(‘intermediate_image_sizes_advanced’, ‘remove_default_image_sizes’);
Looks like you can hook into the wp_create_thumbnail filter: function wp_create_thumbnail( $file, $max_side, $deprecated = ” ) { if ( !empty( $deprecated ) ) _deprecated_argument( __FUNCTION__, ‘1.2’ ); $thumbpath = image_resize( $file, $max_side, $max_side ); return apply_filters( ‘wp_create_thumbnail’, $thumbpath ); } So just do your manipulation, and return the result to wp_create_thumbnail.
A majority of the answers covered how to stop creating future default image sizes but this doesnt account for creating any custom sizes in your theme but here is another solution to add to functions.php: function wpse_240765_unset_images( $sizes ){ unset( $sizes[ ‘thumbnail’ ]); unset( $sizes[ ‘medium’ ]); unset( $sizes[ ‘medium_large’ ] ); unset( $sizes[ ‘large’ … Read more
I agree with david-binda – great question! I’ve run in to this problem on a number of occasions and come up with a solution that works pretty well. While I do like the idea of adding a shortcode to insert the image with classes as suggested by pavlos-bizimis I don’t think it really solves the … Read more
This was (finally) fixed to Gutenberg (and will be applicable for both the image and the gallery blocks); and will add an option to WordPress options’ database table. this was done in https://github.com/WordPress/gutenberg/pull/25578 and https://github.com/WordPress/gutenberg/pull/25582 It’ll be added to WordPress 5.6 but it’s already available in the Gutenberg plugin. To link the image to the … Read more
<img src=”<?php echo get_template_directory_uri().’/images/sample.png’; ?>”> Try this. It should work. You have to concatenate the results from get_template_directory_uri() and your images directory in echo.
Philipp, anything is possible if you set your mind to it. You can solve your issue by extending the WordPress image editor class. Note I’m using WordPress 3.7 – I haven’t checked any of the below code in earlier versions and in the latest 3.8 release. Image Editor basics WordPress has two built in classes … Read more
This isn’t a really good solution since it’s a newer CSS solution and it’s only working in 78.9% of users browsers, but there are a few polyfills that can overcome that object-fit-images and fitie img { display: block; overflow: hidden; width: 400px; height: 400px; -o-object-fit: cover; object-fit: cover; } Ideally it would be better if … Read more
