My c# application gets personal JPG  pictures from the user.
These pictures have to be displayed only  in the application and not available for other users.
How do I  encrypt or hide these pictures or images? Is there is another way without encrypting  each file?

That depends on various factors:
-  Are you protecting images from professionals or ordinary users.
-  How often is an image displayed.
-  are you tight on computer resources or are you willing to sacrifice a lot.

Encrypting / decrypting pictures and displaying them needs a lot of resources. To minimize resources needed you can encrypt a part of the image and decrypt it into memory and display it faster and using less resources.
