Will an automatic photo description explain what my post means?
The short answer
Not necessarily. Automatic alt text identifies visual features; it is different from a description you write for a screen reader. Explain what matters in your photo. If your Instagram editor offers an alt-text field, use it; otherwise put the essential description in the post text.
What this answer is based onWhat to do
Write for someone who cannot see this particular picture. For an invitation, the date and location matter more than the colour of the border.
- Identify the one thing the picture adds. Draft a short description of that meaning; copy any essential date, price or instruction into the ordinary post text.
- Check the image’s editing options. If an alternative-text field is available, add your description there and save it. If not, include the description in the post itself.
- Read the text without looking at the image. Can you understand the announcement? Check names and numbers against the picture, then review the saved post for missing details.
The situation
Example: a café posts a picture of a notice saying it closes at 16:00 on Friday. “A sign in a window” misses the point. Put the early closing time in the post text too.
The situation and an improvement
The announcement only makes sense to someone who can read the picture.
The essential message is available in text, with a useful image description where supported.
More examples
A chart without its conclusion
An account posts a sales chart with no explanation.
What to do
State the trend and the figures readers need in the post; a short alt text alone may not explain a complex chart.
A group photograph
The automatic description cannot explain why the photo matters.
What to do
Describe the event and relevant visible action. Do not guess anyone’s identity or personal characteristics.
