How Do I Change the Default Thumbnail in WordPress?

Changing the default thumbnail in WordPress can be a fairly simple process, though it can be a bit time-consuming if you’re intending to change all of your images. To change the default thumbnail, first open your WordPress dashboard and click the “Appearance” link in the left-hand column.

From there, scroll down until you see the “Gallery” section, and click on the “Thumbnails” link.

On the thumbnails page, you’ll see a list of all of your images. To change the default thumbnail, click on the image you want to use as the default, and then click on the “Set as Default” button.

You can then select a new thumbnail for the image, or you can keep the current thumbnail if you want.

If you want to change all of your images’ default thumbnails, you’ll need to follow the same steps, but you’ll need to click on the “Images” link instead of the “Thumbnails” link. Then, you’ll need to click on the “Set as Default” button for each of your images, and select a new thumbnail for them.
