OneClickContent – Image Detail Generator

OneClickContent – Image Detail Generator is a free, bring-your-own-key plugin for enhancing existing WordPress images with AI-generated metadata.

Use your own OpenAI or Gemini API key to generate:

– alt text

– image titles

– captions

– descriptions

This plugin is focused on metadata generation for images already in your Media Library. It does not create images.

SVG attachments remain available for audits and manual editing. AI generation skips them without making a provider request.

Key Benefits:

– Improve SEO for image search and content relevance

– Improve accessibility with descriptive alt text

– Save time on repetitive metadata writing

– Use your own provider account and models

– Bulk-generate metadata across your library

– Control which fields get updated

– Run preflight counts and dry runs before making provider requests

– Review, edit, approve, reject, or defer field-level suggestions

– Process resumable batches with pause, resume, cancel, and retry controls

– Restore individual fields or complete batches from immutable change history

Quick Start

• Keep overwrite disabled for the safest starting point.

• Open Image Metadata > Image Library.

• Find an image and click Preview.

• Compare the current and suggested values. Preview does not change the image.

• Edit a suggestion if needed, then click Use this suggestion for each value you approve.

• Use Generate when you want the current plugin rules applied automatically. With the recommended defaults, Generate fills empty selected fields and preserves existing metadata.

Whitespace-only fields are treated as empty. SVG attachments can be edited manually, but AI generation skips them.

How to Process a Batch

• Open Image Metadata > Dashboard and review what is missing.

• Under Choose what to run, select the fields and a small starting batch such as 10 or 25 images.

• Leave the mode on Preview only – change nothing, then click Run Preview.

• Review the estimated images, fields, provider requests, and cost.

• Open Advanced batch options and choose one of these modes:

• Create suggestions for review saves proposed values without changing attachments.

• Fill missing fields applies values only where selected fields are empty.

• Overwrite selected fields replaces existing values only when overwrite is enabled and immediately confirmed.

• Run the batch, then open Image Metadata > Batches to monitor it.

Batches run in the background. The Batches screen provides pause, resume, cancel, and retry controls, so the original browser page does not need to remain open.

Your field, batch-size, mode, ordering, and missing-field choices are remembered when you run the form. Overwrite confirmation is never remembered.

How to Review and Restore

Open Image Metadata > Image Library and filter for images with suggestions ready. Each suggestion can be approved, edited before approval, rejected, or left for later.

The plugin records metadata before applying a workflow change:

• Open Image Metadata > History to restore an individual field.

• Open Image Metadata > Batches to restore a completed batch.

A normal restore protects values that someone edited after the recorded plugin change. An individual field can be force-restored only after explicit confirmation.

Recommended First Run

• Enable only Alternative text and Title.

• Keep overwrite disabled.

• Preview 10 images.

• Check several results against the images and page context.

• Run Fill missing fields on a small batch.

• Confirm the results in the Image Library before increasing the batch size.

Advanced workflow settings contain processing limits, request ceilings, retry behavior, editorial guidance, context controls, overwrite permissions, history retention, reports, capabilities, and WP-CLI support. Most sites can leave these settings at their defaults.
