# Output inspection: Writing Useful Alt Text from an Image

Describe the information the image contributes instead of listing every visible object. Review the result at its intended size and inspect details that previews can hide.

## Practical review sequence

1. Preserve the original input and note its important limitations.
2. Apply the smallest change that addresses the current task.
3. Compare the result with the source at the intended display size.
4. Record settings and uncertainty before the result is reused.

This public workflow document covers one bounded quality-control task. It is intended as a repeatable reference rather than a substitute for checking the source material and the final output directly.

## Summary
Effective alt text should focus on the information an image contributes rather than listing every visible object. Review the final output at its intended display size to ensure all details are accurately represented.

## Themes
- Alt text best practices
- Image description workflow
- Quality control process

## Key takeaways
- Alt text should focus on the information an image contributes rather than listing every visible object.
- The practical review sequence requires preserving the original input and noting its limitations.
- The smallest possible change should be applied to address the current task.
- Settings and uncertainty must be recorded before an output is reused.
- This document is a bounded quality control task rather than a substitute for checking source material.

## Insights
- Effective alt text prioritizes the information contribution of an image over a literal inventory of its contents.
- Previewing images at their intended display size is necessary to catch details that are obscured in smaller thumbnails.
- The provided workflow is designed as a repeatable reference rather than a replacement for human verification of the final output.

## Open questions / gaps
- What specific criteria define whether an image's information is considered important versus trivial?
