Quad is already used to display an image and the cube is 3D model. So, we will delete the cube but we need the Quad. Quad is already displaying the namecard Image that is placed on the material. So we will just change the image . Now we will take our image from the desktop and change the Albedo here. Then this Quad will show the image that we put onto it. Drag the image in the textures in the unity.

Now in Quad go to materials . Then click on Albedo and select the texture. In order to change the image target we will bring our own target in the streaming assets folder. We will drag the target 2.jpg in the streaming assets folder. Now go to image target and name it. Target name and target path will be same only we need to add .jpg with the target path.

Naming target and target path

Our image is stored as streaming assets. Now you can see that the Quad attach image is having black background . To remove that go to its settings. Now go to sprite (2D and UI) and click on apply.
