Typically for an animated prop you will have two (2) static images (Start & End) an one (1) animated image (Loop).
You use the static Start image to show the prop before the loop starts.
Then you switch to the animated Loop image at the frame needed.
When the loop has completed you then switch the sprite to the static End image.

HERE and you will see what I mean.
