Describe the image in its actual page context
Check an AI-generated image description against the artwork and the purpose of the image on the page. Keep visible evidence separate from project information supplied by an approved source. A plausible description can still invent a client, material, location or result that the image does not establish.
Google's image guidance connects useful alt text with page context. The review method below is my editorial recommendation, prompted by 29 October multimodal-search coverage. It is not a promise of greater visibility from a particular wording formula.
Separate three kinds of information
First identify what the image visibly contains. Then identify approved project context that the surrounding page explains. Finally identify claims the model inferred without evidence. That last group should be checked or removed rather than quietly promoted into public copy.
For a fictional portfolio image, a model might recognise a green package and textured label, then call it a sustainable skincare launch for a Portuguese client. Colour and layout may be visible; sustainability, sector and client location need separate evidence. An attractive image does not validate those additional statements.
Choose the right job for each text field
Alt text, captions and the main project description serve different purposes. Avoid filling every field with the same long marketing statement. Give the reader the information needed to understand the image in this setting, with fuller context where the page can explain it properly.
Decide whether the image contributes information or is decorative. Review an informative diagram differently from an atmospheric background. Do not force a list of keywords into an image description simply because the page targets a service query. Accurate, useful wording is the requirement; there is no universal phrase that makes a portfolio citable.
Give the assistant a constrained evidence brief
Supply the image, its role, the adjacent heading and any approved project facts. Ask the assistant to flag uncertainty instead of inventing missing context. Require a reviewer to compare the proposed description with the actual export, especially after the artwork changes.
A useful working instruction is: describe the visible information relevant to this page, use supplied project facts only where needed, and list uncertain identifications separately. That instruction is a starting point for calibration, not a substitute for reviewing the result. Do not expose private client notes merely to make a prompt more detailed.
Review a sample before scaling the pipeline
Choose a representative set: a screenshot, a packaging image, a diagram and a decorative asset if those exist in the portfolio. Check invented details, missed information and unnecessary repetition. If the site has multiple languages, have the translated descriptions reviewed for meaning rather than assuming a fluent translation preserves every claim.
The image-delivery test addresses whether the file can travel. This review addresses what the page says about it. JQ's prompt-engineering work can calibrate that distinction using approved examples. Scale only after the reviewer can explain why the accepted descriptions are useful and accurate.
