I have the mobile site turned on in my control panel, and my security is set to the largest size of original, and not protected for the gallery in question. When I visit my site from an iOS device such as an iPhone or iPad, I cannot figure out how to download an image. When I long press on an image and save, it saves a completely black image to my camera roll.
Specifically I am trying to offer users iOS backgrounds for download, and allowing them to do so from my mobile site makes the most sense. Is there a way to do so?
