I need help to about createing imageTarget.

I'm Add target in diveces databases and download unitypackage

and import the package, set my target to imageTarget Object

but is not tracking and find

have I forget anymore???

Is it possible to create a game with using image target? 

No, you need to use the ARCamera, which is devoted to the rendering of the video background as well as controlling the field of view and the camera position based on the detected trackables.

it is possible to see the image target of vuforia with the main camera of unity 3D?

I tried to do this, on the modality run in backgroud i see the image target but when i make an app (android or pc app) with the main camera i don't see my image target, i see only the blue background.

how can i do this?

You need to compile the shared libraries. See: https://developer.vuforia.com/resources/dev-guide/getting-started-android-native-sdk
