I have an array in Unity. I want to assign an image based on the gameobject's tag

This is in Unity 2018.4.20f LTS. I have a lot of 3d gameobjects that I’m storing in an Array. I have searched around but can’t find a way to do it. Right now I have a panel and a bunch of white box images as placeholders. When I pick up an object a white box pops up on my canvas panel.

What I would like to know is there a way to grab an image and display it in place of the white place holder image based on the gameobject’s tag? Like if it is tagged hammer and I have a hammer image display that image?

If so could someone point me in the right direction on how I would accomplish this?

Can you use a String to reference the object’s tag? I needed to instantiate objects into an array based on their tags, and I did it something like:

GameObject OriginalObject = Resources.Load("Folder/" + PrefabReference) as GameObject;

The PrefabReference just being a String with the name of the prefab. Then just instantiate OriginalObject to the array:

ObjectArray[number] = Instantiate (OriginalObject, new Vector3(1f,0,20f), Quarternion.Identity);
