Visualizing an image in a stack with the threshold filter

If you have a stack of images, let us say 1 to 100. By using the threshold filter, is it possible to visualize the middle image, say 50. Instead either the first or final image in the stack?

I am using the threshold filters because I have many 0 data points in my array. Thus, set a negative and positive threshold value to only show the non-zero values from -2 to 2.
