The short answer
Put essential explanations in readable page text, not only in decorative graphics or screenshots. Images can support understanding, but the main answer and critical qualifications should remain accessible without them. This also makes editorial correction and reuse more straightforward.
A worked example
A fictional article uses a checklist illustration with four green checks. The visible body should still explain audience fit, source dates and commercial scope. If the image fails to load, the reader can complete the review from the text. Decorative artwork can then contribute to the supplied design without carrying the whole answer.
A practical checklist
- Identify which information a reader needs to act correctly. Place that information in the article body with clear headings and sensible reading order.
- Use images for demonstrations, supporting diagrams or decoration. Add contextual text alternatives and visible explanations when the image contains essential information.
- Test the page with images disabled or unavailable. Check whether the direct answer, warnings and next step still make sense.
What to avoid
Avoid turning long paragraphs into image assets merely to preserve a screenshot's visual layout. It can make text harder to read, adapt or translate. Design fidelity should preserve the reference's hierarchy while keeping the actual content usable at different widths.
A useful follow-up
Should every hero illustration repeat the article's entire answer?
No. Keep the answer in text and let the illustration support the page without becoming its only source of information.
