Either way, it sounds as if the person running the site has set different security levels for different images. Treating the background image differently from others could be a reasonable thing. All I know about this is what I've run into myself, so others might have more to say.
If the other images don't give you the option to save on a right click, that option has probably been disabled to protect the images from being copied. There are ways around this, which is the reason it's not a very high level of protection, but if a site makes this strong of a statement about not wanting their images copied, my personal response would be to respect that.
If you're asking why you get an option of "download" instead of "save" on the background image, in my experience it would mean that the site provides a specific file - not the image you see on the page - to be downloaded to your computer. An example that might be relevant is a site I use fairly often that provides free background tiles and clip art (in exchange for your looking at a lot of CPM ads). The image on the screen is often much smaller than the one that would actually be used, so if I click on an image to say "I want this one," the site gives me a different file to download. I've also seen it used on sites where visitors are allowed to see thumbnails, but in order to view and/or download the large image they have to be a member or pay a fee.
I don't know if this answers your question or not?
