Working with Image and object targets in same database

Hi,

I'm developping Vuforia app with Unity, and i' m trying to detect some 3D targets, but image targets too.

When i try to start the app, i'm able to detect the 3D objects (all of them) but not the image target...Tryed with the sample chips image.

The databases contains 4 objects and 1 image.

I found an old link about combining these types of target, but it's not up (very old link...no page)...

Any idea please ? 

Thanks in advance
