Today, I am making a new website for a client. I’m setting up a wordpress on my local server. As usual I link all the libraries I need, the JS plugins and I modify the common WordPress settings in the dashboard. When I set all the media sizes to “0”, I just realised that WordPress is still resizing the images to a medium large (called “medium_large”) size, wich is about 768px wide. After a quick search on internet, I found a log from November 10th 2015 about responsive images in WordPress 4.4.
In this post you can read that WordPress has a new default image size, called “medium_large”. This size has been added to better take advantage of responsive image support.
But what if you have no need for responsive images, or you just don’t want the images to be resized at 768px ?
You can simply manualy update this option in your “functions.php” file using those two lines:
//delete medium_large thumbnail size update_option('medium_large_size_w', '0'); update_option('medium_large_size_h', '0');
Or you can go in your database to modify the option in the “wp_options” table.
