Oomph WP Inline Image Resize


Resize images on the fly! Great for theme developers who add image sizes to their theme after image assets have already been added to the image library – images come out the right size, every time.

Works great for both single-site and multi-site installations. Multi-site installation requires SUNRISE to be set and wp-content/sunrise.php to be populated – Instructions are given within the plugin.


  1. Upload oomph-wp-inline-image-resizer to /wp-content/plugins/.

  2. Activate plugin through the WordPress Plugins menu.

    2a. On a MULTISITE installation, this plugin must be activated network-wide.

    2b. On a MULTISITE installation, code must be added to wp-content/sunrise.php and SUNRISE must be defined in wp-config.php. The code is provided when the plugin is activated.

    2c. On a MULTISITE installation, the .htaccess file must be updated. Instructions are provided in the plugin.

  3. Now all attachments displayed via wp_get_attachment_url() will be resized according to the image size in the theme.
