Have you associated a thumbnail image with your theme? In the Look and Feel settings of your site pages in the Site Administration screen, notice that each available theme has a thumbnail image. It’s time to dress up your theme with stylistic appeal by creating a thumbnail image for it.

Here are the steps for setting up a thumbnail image for your theme:

  1. Create a thumbnail image. Make sure it’s 150 pixels wide by 120 pixels high. You may want to take a snapshot of your theme and re-size it to these dimensions. It is very important to abide by these exact dimensions or your image won’t display properly as a thumbnail.

  2. Save the image as a .png file named thumbnail.png and place it in your theme’s docroot/_diffs/images folder (create this folder if it doesn’t already exist). On redeployment, your thumbnail.png file automatically displays as your theme’s thumbnail.

Now, when you visit your the Look and Feel settings, your theme’s thumbnail displays along with the thumbnail images of other themes available to your site.

Congrats! Now you know how to create a thumbnail image for your theme!
