Image Access filter lets you view only the images that you have access to.
To enable the "Image Access" filter-
1. Log in to Planet Explorer and then go to Filters.
2. Enable the "Image Access" filter and click Apply Filters. Now, you're all good to access images that you have access to.
By disabling the "Image Access" filter you can view all the images that you do not have access to. Though you can see the details of the image, it will request you to purchase the imagery. As shown in the screenshot below.
