How to Create a Thumbnail

Now that you know what a thumbnail is, we’ll show you how to create them using the cPanel tool called Thumbnailer.

NOTE: The images you would like to create thumbnails for must already be uploaded to your cPanel account.

  1. Login to your cPanel account.
  2. Under the Files subheader, click on the Images icon.
    Create a Thumbnail Image - cPanel
  3. Click on the Thumbnailer link.

  4. Locate the image folder that you would like to create thumbnails for. You must thumbnail the entire folder so you may want to create a new folder and move all the images there.
  5. Click the Thumbnail button next to the folder containing the images you want to thumbnail.

  6. Once a selection is made, cPanel will allow you to specify the percentage (%) by which you want to scale the width and height of your images. Enter the percentage in the first field under Scale Percent.

    NOTE: By default, the Keep Aspect Ratio checkbox is checked. This will maintain the width and height ratio so that the image does not appear stretched.
