Expression/Condition Help: Show image after 4th change of form field

Can I get some help figuring out how to add a specific condition? I am trying to build a prototype where upon entering 4 numbers into a form field, an image appears.

Currently I have created an Event where "on Change" of (selected form field) "Show" (image). Like I mentioned, I need to add a condition where the change occurs after four characters are entered instead of one. Any ideas what that condition would be?

Thanks!
