Question [Q] Trying to find a specific image

Hi everyone,

So I ended up loading up CyanogenMod on my S4 ... I did an update to a nightly build , long story short .. Its stuck in a reboot loop. So now i'm wanting to restore it back to a US Cellular/ Samsung's S4 Image of Android 4.2.2 or 4.3 . Would anyone by chance happen to know where i could find a Samsung System Image at? Any help with this would be greatly appreciated.. :/
