Resamples images after they are resized in the post editor. This makes them look better and download faster.
This plugin requires gd to modify the image files. Also, PHP must have write access to the wp-content/ directory. If you prefer, you can create the wp-content/imagescaler/ directory and give PHP write access to that instead.
As long as you meet the requirements, installation is easy. Just upload
imagescaler.php to the
/wp-content/plugins/ directory, and activate it through the Plugins tab in WordPress.
Once installed, every time a new post is created or any post is updated, the plugin will check all the images in it and see if they need to be resized. Posts that were written before the plugin is insatalled will not be changed unless they are updated.
If you require valid html, go to the options tab in the admin panel, and then go to the ImageScaler tab. Check the box that says "Force strict xhtml" and click "Update Options".
If you decide to uninstall ImageScaler, the resized images (stored in /wp-content/imagescaler/) will still be used, but images in new posts will not be resized.
