Use case scenarios and the use of screenshots?

Question

I have been asked to create an use case scenarios for the project I am currently in .Though there are some excellent templates on the internet about how to structure a use case scenario,I was confused about whether screenshot's of the actual interaction should be part of the use case scenario and if the answer is yes,how many screenshot's are we looking at ?

Assuming I do insert screenshots ,I was thinking along the lines of

Ideal situation

• Mockup #1 (Before state)
• Mockup #2 (After state)

Exceptional case

• Mockup #1 (Before state)
• Mockup #2 (After state)

I am just confused about this since there could potentially be several screenshots and I wonder if really thats the way to construct a use case scenario

You need as many screenshots as necessary to adequately communicate the design to the customer. Though, "screenshot" doesn't necessarily mean an actual screenshot. A hand drawing on a piece of paper is often sufficient. In fact, you almost certainly want something low-fidelity unless the design has specific design constraints. If the screenshot is an actual screenshot you may find your customer nitpicking colors and fonts rather than focusing on the layout and flow of the design.

Don't look at the problem by asking "how am I supposed to write a scenario"?". Rather, ask yourself "how can I best communicate the use case to the customer or product owner?".
