Make the background transparent, not white, in your paint program. Then use a transparent shader in Unity.

If you are using Microsoft Paint, it will not work. Instead, use GIMP or Paint.NET. Then, you can set the background to be transparent, as it is not available in Microsoft Paint.

If you are using photoshop .Make the image background transparent and then Save the image as photoshop format and then attach it to your unity quad object.
