I want to stop wordpress for generating thumnails-CodePudding

My WordPress website is generating thumbnails for my images I want to prevent WordPress from doing that how can I achieve the same?

CodePudding user response：

Consider searching for these particular problems, because this took me 5 seconds to find this plugin: https://wordpress.org/plugins/disable-generate-thumbnails/

CodePudding user response：

You can follow these steps for the same :

Step 1: In Admin Panel Go to Settings -> Media.

Step 2: Now Uncheck (Crop thumbnail) If it's Checked.

Step 3: Set at Thumbnail size, Medium size, and Large size the Width and Height to

You may use the remove_image_size() method like so:

add_action( 'init', 'so_73173777_remove_image_sizes' );
function so_73173777_remove_image_sizes() {
    remove_image_size( '1200' );
    remove_image_size( 'portfolio-full' );
    remove_image_size( 'blog-medium' );
    
    /* etc ... */
}

For removing default WP sizes:

add_filter( 'intermediate_image_sizes_advanced', 'so_73173777_remove_core_sizes' );
// This will remove the default image sizes and the medium_large size.
function so_73173777_remove_core_sizes( $sizes ) {
    unset( $sizes['small']);
    unset( $sizes['medium']);
    unset( $sizes['large']);
    unset( $sizes['medium_large']);
    return $sizes;
}

That code snippet combines all of the techniques required to disable all of WordPress generated images (leaving only the original uploaded image).

// disable generated image sizes
function hipl_disable_image_sizes($sizes) {
    
    unset($sizes['thumbnail']);    // disable thumbnail size
    unset($sizes['medium']);       // disable medium size
    unset($sizes['large']);        // disable large size
    unset($sizes['medium_large']); // disable medium-large size
    unset($sizes['1536x1536']);    // disable 2x medium-large size
    unset($sizes['2048x2048']);    // disable 2x large size
    
    return $sizes;
    
}
add_action('intermediate_image_sizes_advanced', 'hipl_disable_image_sizes');

// disable scaled image size
add_filter('big_image_size_threshold', '__return_false');

// disable other image sizes
function hipl_disable_other_image_sizes() {
    
    remove_image_size('post-thumbnail'); // disable images added via set_post_thumbnail_size() 
    remove_image_size('another-size');   // disable any other added image sizes
    
}
add_action('init', 'hipl_disable_other_image_sizes');

The only editing that may be required is for that last function, where “other” image sizes are disabled; there you may want to edit the another-size slug to match any other sizes that you want to disable, or if there are no other sizes, simply comment out or remove the line.
