Additional Image Block Settings

WordPress is great at simplifying the management of your content, including images. In the previous section, we described the Image Settings available for image blocks. In this section, you can learn more about the advanced ways you can customize your images.

By default, the drop-down menu labeled Link to is set to None. In this case, the image is not clickable.

Alternatively, the Link Settings allow you to control what clicking on the image does. For instance, you can select the Media File option. This redirects the user to a page that displays the image as it appears on the server when they click on it.

The Attachment Page option redirects the user to the page that displays the image as an attachment. This is a more secure option because the URL will not display the path to the file on your server. This also allows users to comment on the image, as long as comments are enabled.

The last option: Custom URL allows you to enter any URL you want to redirect the user to when they click on the image. If you select this option, you will need to enter the entire URL into the Link URL field.

Regardless of which option you select, the following table lists the additional options and a brief description of each one.

Link SettingDescription
Open in New TabBy default, this setting is disabled. Click the toggle to enable it if you want the link to force a new tab open. Otherwise, the link will open according to the user’s browser settings.
Link CSS ClassIf you are using a custom CSS class to design your links, you can define the class in this text field.
Link RelThis text field allows you to enter the value for the rel attribute of an address (a) tag. The most common use for this attribute is for SEO purposes.


If you are using a custom CSS class to design your images, you can define the class in the Additional CSS Class field.

Now, you should be familiar with customizing image blocks to manage your user’s experience with images. If you want to learn more about customizing WordPress, be sure to check out our WordPress Education Channel.
