Why is my inbuilt app disabled ?

After kitkat 4.2.2 update , I am unable to find the photos inbuilt application of my samsung galaxy s4 . I have checked the disabled apps list as well. Still couldn't find it.

I've Googled "Inbuilt" but found nothing. Do you mean builtin? When you say photos do you mean your gallery? A brief search shows that there are a lot of complaints about the S4's camera and gallery apps. I would say try restarting it, even though I'm sure it's probably restarted itself after the update. If your app doesn't return you may consider a factory reset or getting another gallery app from the Play Store.

The Photos app is part of Google +. Has you disabled it?

Samsung may also have removed the app from their version of Android.
