Good questions.

If you right click on the Image Threshold VI and choose Help, it will take you to the reference manual on this VI. It clarifies ...

Image Dst is a reference to the destination image. If Image Dst is connected, it must be an unsigned 8-bit image.

So, you don't need to get another image. Your diagram is very close, but make the dst be the correct type of image. If you run it the way you have it, you will receive runtime errors at that node.
