Prevent WP Lightbox on External Links

Hi

I use WP Featherlight on my site and it is a fantastic plug in for my site that has a large amount of image galleries.

Recently, I’ve noticed that if I link directly to an image that is hosted off of my site – I frequently post links to images I create that are ‘hosted’ on Dropbox, for example – the WP Featherlight plug in on my site will try to load the image when you click on it, instead of loading the link/page in a new browser tab or window. Since the image is technically not hosted on my site, the image is not loading (i.e. its not ‘remote loading’ the image, which is the proper behavior).

Is this a bug in WP Featherlight? I would think it should know that the URL is not on my domain and therefore, it should not try to load the image in WP Featherlight on my site.

Or, is there a way in these circumstances to prevent WP Featherlight from loading in these instances when I am linking to an external image on Dropbox (or wherever).

If you go to this page on my site you can see an example of what I am talking about in the comment from May 17, 2021 from Kimberly and my response to her.
