It appears this can be done by setting the main image size to “Original”. Will this slow the site down? Is there a better way?
Thanks!
Sorry, I was on vacation the past week, without access to a computer.
Some lightboxes support a dedicated “download” button, such as LightGallery, Fancybox3, Venobox, PhotoSwipe 4 etc.

No, it will not slow your site down. It might take a bit longer for the lightbox to come up, but that is a user interaction activity, and does not impact how fast your site itself comes up.
Based on your comment, I can assume the lightbox can be changed while keeping the Phtonic plugin?
Sorry, I am not following you. Photonic is a gallery and lightbox plugin, as the name implies. It is bundled with a boatload of lightboxes (15 at present). You can take your pick from Photonic → Settings → Generic Options → Generic Settings → Inbuilt Lightbox Libraries. All the lightbox scripts that I have mentioned are bundled with Photonic and fully supported.
