Be sure the image isn't already at 100% size (you can check using the Size and Position dialog box). For example, if the source image is 600 pixels by 400 pixels and you didn't scale it down after importing it onto the slide, the Zoom feature will have no effect, and I'm pretty certain Storyline removes the Zoom icon when previewed and published in this case because it can't zoom it beyond 100% of the original imported image size.
