dude, this looks great and i will try it really soon.
btw. in iOS 7 (for both iPhone and iPad) there's this new parallax effect (hard to explain what it is so you might just want to look it up on apple.com) and if you'd like to support this effect with your wallpapers, then you might want to consider adding 200px to all sides, because otherwise all regular sized wallpapers would get zoomed in, which make them look kinda blurry and not very good. well, this might not be that troublesome with walls that are blurry or just color gradients to begin with, but i thought i just tell you.
well, here's a link for you from where you can get more information on this.
First thx my friend and yeah I also heard something about some people having problems with wallpaper things in iOS7 due to changes by Apple. Sadly I don't own an iPhone 5 - I have an Android and can't really try how these walls are looking for real. I bet they doesn't look @ 100% of it's beauty, by definition many walls are looking better on my 1080p desktop led screen compared to my phone SAMOLED 440x800 screen. Again thx for the writeup.
