Step 1: Install and Activate the Regenerate Thumbnails Plugin

To begin, download and install the “Regenerate Thumbnails” plugin by searching for it in the WordPress plugin directory or uploading it manually by downloading the zip file and uploading it. Once installed, activate the plugin.

Step 2: Navigate to the Media Library

Next, go to your WordPress dashboard and click on “Media” on the left sidebar. This section shows all the images and media files stored on your website.

Step 3: Select Images

Select the images that you want to regenerate thumbnails for. To regenerate thumbnails for all the images on your website, leave this step and move to the next.

Step 4: Regenerate Thumbnails

After selecting the images, find the “regenerate thumbnails” option at the top of the media library page, and click on it. The plugin will automatically regenerate the thumbnails for the selected images.

Step 5: Verify Changes

Once the regeneration is finished, refresh the page and check if the images are displaying in the correct size. If you regenerated thumbnails for all images, ensure that the page load speed has not been affected adversely.

After following these simple steps, you will have regenerated the thumbnails for your website’s images.
