Hello Filipe.

Unfortunately, there is no built-in feature that'd help you achieve this, but you will be able to do it with some simple CSS.

I presume you have an image column, where all your images are located.

For you to be able to still edit that column from back-end, you will need to add the CSS in the <style>...</style> tags when you're creating the page, like this:

<style>
.wpdt-c td.column-image {
  pointer-events: none;
}
</style>
[wpdatatable id=1]

Where "image" within "column-image" is the columns name.

There's another way of doing this, avoiding CSS - but that'd be adding the column as "String", with editor input type - One-line edit, and then adding just <img src="link-to-the-image"> without any <a href... tags.

I hope this helps.

Best regards.
