Hi and welcome to the Forum!
I have moved your post so that we can help you better here rather than annoying members in the other ongoing thread. If you do have a question, after searching first please start your own thread rather than hijacking another thread, it gets quite confusing for members and is against Forum Rules.
I take it you have taken some photos and they are not appearing in your camera roll in the photos App. Well the first step when an app behaves strangely is to close it completely and then relaunch it. From the home screen do the four finger swipe up or double press the home button to reveal your multi task bar. These are all the apps that you have opened at one time. Long press both the app until it jiggles and a red minus sign will appear above it. Press the minus sign, this will close the app, not delete it, now press the home button to return to your screen. It's also a good idea to close all these apps, as it helps the iPad run smoothly.
Have another try and see if they are now appearing for you. Another thought is that maybe you had the camera set for video recording rather than taking photos. When in the camera app you will see in the bottom right corner the slide to switch from camera to video, might be an idea to look at that one photo that has appeared to see if it is a photo or a video you have recorded. Anyway have a look, take some more photos and see how you go and let us know.
