While removing bloatware from my GS3 using ROM Toolbox Pro, I deleted the stock pictures Gallery, mistakenly thinking that Quickpic is all I need. After a reboot, I found that my lock screen picture had changed. I navigated to Settings | Display | Wallpaper | Lock Screen | Select Wallpaper from...and the options to change my pic were missing! I could not select a lock screen pic. I downloaded a replacement stock gallery app, SecGallery2.apk, but the app would not install. I decided to replace my stock camera & gallery app with the new photosphere camera & gallery app. Photosphere successfully installed (which is badass), but my lock screen options are still missing. I tried to select a pic with the new gallery, but it only works as a wallpaper. I'm stuck with the gay little dandelion pic on my lock screen. It's a minor inconvenience, but let's face it- we like our phones running perfectly or we wouldn't be on this forum. Any ideas?

My S3 is rooted, but I'm still running Jellybean 4.1.1...I don't need a custom ROM because NOVA does all I need. For now.
