Put it into practice
- Load the intended data and wait for it to render.
- Check images, fonts and chart labels.
- Capture a stable state and compare it with the on-screen version.
What this looks like
A report screenshot is taken after its graph and filters have loaded, not during the initial skeleton.
A detail to keep clear
Do not present a loading state as the completed feature unless loading behavior is the subject.
Using MockupX
MockupX accepts pasted, dropped and uploaded images. Screen capture depends on browser support and your permission. The phone-transfer flow uses a temporary upload session. Prepare your source image before decorating it: a frame cannot recover unreadable text or remove sensitive information for you.
Check the result
Keep the original screenshot, then review the exported file at the size where people will see it. Check the message, the visible interface and the final crop separately. For a handoff, record the destination and the approved file so another person can distinguish the final version from a draft.
References and further reading
Use the official references for format behavior and current destination requirements. The composition advice above is a practical design approach, not a promise of platform approval.
