Please forgive the mess.  As soon as I can, I’ll be buying ($19) a specific gallery layout.  What it will do is give you a lightbox that has a download link in the upper right of the screen (not sure what it’d look like on mobile), so that you don’t have to bother with the right-click/menu crap a person has to use in order to save the image.  All this stuff is dependent on the browser and viewscreen (desktop/tablet/mobile), and it’d be far easier to have a program give you a download link (the standard download arrow).

Have also gone through and made several galleries, though you won’t be able to tell unless you’re viewing the specific gallery pages or the All Wallpapers page(and the change in the menu).  It’s far easier to use these premade galleries so that the page views them properly.  But until I pay for the format I prefer, I don’t really trust the view you’ll get.  The free version is okay, but it’s not really meant for a lot of images.
