问题
I am trying to track an image target rendered by vuforia. I would like to set up a web app where I can upload a new image target that will be downloaded and integrated automatically by the app.
Can I set a folder from which I automatically can use all existing image targets to track?

Well for using image targets different than vuforia provided you have to create your own database. You add a new database than add targets to it. You have to be careful with the ratings of your images. Then you can download this database as a unitypackage and you can see it has two image targets and .dat and .xml file in it:
Then you can use this database using ImageTargetBehavior. This database can be your folder where you want to use existing image targets to track.
