Question Regarding Promo "Splash" Images

Is there a place I could find them all together? A promo gallery, I guess?
I mean like these: http://i.gyazo.com/508f02bafb2f0f8c43a885983f7b3157.png but without the text
I checked the Wiki and can't seem to find those images stored anywhere. I dig the style of the game and wanted to maybe look back on old splash images like these. ;w;
edit: Nevermind, I'm a dummy, I forgot that they're likely all hosted on the Facebook page, granted I'll have to do some digging to find them all. I'll get them all in an IMGUR album shortly, though.

Yeah, I'm a little bummed that more of these aren't higher-res, but thankya! Better quality than the older ones on the SK homepage, at least, those aren't even 250 pixels wide. x_x

I'd love for them to have higher resolution pictures for the promotions as well; they'd make really nice wallpapers... *hint hint* Pwease~~~
I would definitely put some in a folder and cycle through them on start-up if there were more available. A google search brings up some, but there isn't really a consistent place for them. Perhaps there needs to be a forum or wiki page with a collection, I know I'd love that.
What I really hate about it is that there are plenty of wallpaper collection sites that have viruses. It's made me very cautious and cynical when looking for wallpapers. The picture page itself may be fine (or not) but the gallery could be dangerous.

FYI, there's also alot of (older) pics in Sega's SK Flickr alblum: https://www.flickr.com/photos/segaamerica/sets/72157626143386429

Ahh yeah, thanks for these!! I'm not sure how I'll organize it all yet so I'm kind of holding off on it for the moment. x_x
In the meantime, though, I don't know who originally posted these but I've had this link bookmarked since I got my laptop. http://imgur.com/a/HYrFU Skyboxes for wallpapers!

A lot of them are available here at what I believe is the maximum available quality.
Though beware they don't look too pretty - jpeg compression and lack of anti-aliasing means they likely weren't intended to be viewed in such great detail.
EDIT: Actually it seems they only recently started using .jpeg - further back you can find ones that are lossless .png but still suffer from a visible lack of anti-aliasing in places that aren't painted over.
I just had the idea of viewing the background image. This is a little frustrating.
