Step-by-step method
- 01
Identify the visual’s role
Distinguish informative photos, charts, text in images and decoration. Describe information needed for the message. A promotional caption does not automatically describe the image.
Output: Role and essential information.
- 02
Write for context
Explain the useful subject, relationship or action without inferring identity, emotion or unsupported facts. For a meme, preserve the text and context needed to understand it. Avoid keyword lists.
Output: Contextual description.
- 03
Explain complex content
For charts, provide conclusion, units, period and essential data. Check each carousel image and the sequence of ideas. Put complete explanation in the post or linked page if the short field is insufficient.
Output: Complex-data explanation.
- 04
Check the published version
Review the platform’s current behaviour, per-image descriptions and final output. Test screen-reader access and crops. A scheduling tool may not preserve every authored field.
Output: Published-version acceptance.
- 05
Maintain each edition
Review numbers, names and alternatives after translation or edits. Identify fictional illustrations. Never turn an explanatory created scene into evidence of a real event.
Output: Language and transformation review.
Fictional acceptance-test scenarios
These proposed cases are not client observations. Adapt data, permissions and acceptance criteria to your authorised environment.
| Situation to exercise | Result to check | Evidence to retain |
|---|---|---|
| A poster contains the date, place and registration link only in the image. | Put useful information in accessible post text; adapt the alternative to the image role. | Post reviewed without displaying the image and successful registration task. |
| A decorative image repeats adjacent text exactly. | Avoid unnecessary repetition where the channel supports an appropriate alternative; check the actual reading experience. | Adjacent text, role and real reading in the channel. |
| An export includes media but omits its alternative text. | Document the loss and separately retain text and associations needed for republishing. | Reconstructed export, missing fields and replacement archive. |
Reusable worksheet
Complete with your authorised observations. These fields are a working template, not observed results.
| Field | Information to record |
|---|---|
| Visual | Role, origin and essential information |
| Text | Short description and longer alternative |
| Release | Platform, version and retained fields |
| Review | Crop, translation and assistive access |
Worked example
Illustrative situation
Fictional example: a carousel shows three steps and a chart whose units appear only in the image.
Decision and expected evidence
Publication adds a description to every image and explains values in the post without inventing client results.
Distinguish the mechanisms
| Mechanism | Purpose | Check or limitation |
|---|---|---|
| Short description | Essential visual information | Adapt to context |
| Post text | Message and longer information | Preserve comprehension |
| Data or transcript | Detail of complex content | Connect it clearly to the image |
Management indicators
| Indicator | What it measures | First action |
|---|---|---|
| Described images | Informative visuals with alternatives | Complete omissions |
| Available data | Charts with values and context | Provide usable explanation |
| Reviewed versions | Actually checked releases | Review each transformation |
Common pitfalls
- Adapt to context
- Preserve comprehension
- Connect it clearly to the image
Frequently asked questions
Must every detail be described?
No. Preserve what serves message and task. Decorative detail can distract from useful information.
Is automatic description enough?
Review it. It can miss text, units, relationships and context or add unsupported details.
How should a chart be handled?
Provide a short description and essential data; do not replace numbers with a vague judgement.
