Generate AI alt text for your images via IMG Alt Gen. No data sent until you connect your account or run a generation.
IMG Alt Gen Pro connects your WordPress site to the IMG Alt Gen SaaS, a hosted service that generates descriptive, accessibility-friendly alt text for your images using AI.
The plugin adds tools in the Media Library and a dedicated “AI Alt Text” admin area so you can:
<ul>
<li>Generate alt text for individual images directly from the attachment screen.</li>
<li>Run bulk generation over batches of media items.</li>
<li>Prioritise images actually used on published content.</li>
<li>Use optional context from posts, products and SEO plugins to improve descriptions.</li>
</ul>
This plugin is an interface to an external service and requires an IMG Alt Gen account with tokens to generate alt text. Core image generation happens on IMG Alt Gen’s servers, not inside WordPress.
<h3>How it works</h3>
<ol>
<li>Install and activate the plugin.</li>
<li>Link your WordPress site to your IMG Alt Gen account using a secure token.</li>
<li>From the Media Library or AI Alt Text screens, choose which images to process.</li>
<li>The plugin sends the relevant data to the IMG Alt Gen API, receives generated alt text, and stores it in <code>_wp_attachment_image_alt</code>.</li>
</ol>
<h3>Data sent to the external service</h3>
No data is sent to IMG Alt Gen until:
<ul>
<li>You explicitly link your site to an IMG Alt Gen account, and</li>
<li>You trigger an action that requires the service (e.g. checking tokens, generating alt text, syncing account status).</li>
</ul>
When you run a generation, the plugin may send:
<ul>
<li>Image URL or image bytes (for better AI support across multiple providers).</li>
<li>Basic site/context info, such as:
<ul>
<li>Attachment title.</li>
<li>Related post/product titles and taxonomies.</li>
<li>Optional SEO context (e.g. focus keyphrase, SEO titles/descriptions) if you enable those integrations.</li>
</ul>
</li>
</ul>

<ul>
<li>Terms of Service: https://imgaltgen.com/terms </li>
<li>Privacy Policy: https://imgaltgen.com/privacy </li>
</ul>
Site owners are responsible for ensuring they have a lawful basis for processing images and any associated personal data before using the service.
<h3>Features</h3>
<ul>
<li>
AI-generated alt text 
Generate concise, human-readable alt text designed for accessibility and SEO.
</li>
<li>
Bulk processing 
Process images in batches while respecting server limits, with progress feedback in the admin UI.
</li>
<li>
Context-aware descriptions 
Use post and product context (titles, categories, tags, product data) to improve relevance and specificity.
</li>
<li>
Published-content focus 
Optionally prioritise images that are actually used on published posts and pages, rather than everything in the media library.
</li>
<li>
WooCommerce support (optional) 
When enabled, product data can be used to improve descriptions for product images.
</li>
<li>
SEO plugin awareness (optional) 
Can read supported SEO plugin fields (where available) to provide better context for the AI model.
</li>
<li>
Role and capability controls 
Restrict who can trigger AI generation or manage account settings using WordPress roles and capabilities.
</li>
<li>
Privacy-conscious by design 
No usage analytics or tracking scripts are injected on the front end. The plugin only communicates with the IMG Alt Gen API to carry out requested operations.
</li>
</ul>
<h3>External service notice</h3>
This plugin is not a standalone alt-text generator. It is an interface to the IMG Alt Gen hosted service and relies on that service to provide AI-generated alt text.
By connecting your site and using the plugin’s features, you agree to the IMG Alt Gen Terms and Privacy Policy. If you do not wish to use an external service, you should not activate or connect this plugin.

IMG Alt Gen Pro

Interface plugin for a hosted service that generates descriptive, accessible alt text for your images.

AI Auto Alt Text Generator is a lightweight, privacy-conscious plugin that uses OpenAI vision-capable models (defaulting to GPT-4o mini, with GPT 5 Mini/Nano options) to create meaningful, screen-reader-friendly alt text and SEO-friendly titles for your images. Whether you add a single image, bulk-process your library, or just want a one-click fix in the Media Library, the plugin handles it all – no manual effort required.
This solution is far cheaper than many alternatives because it cuts out the middle-person. You’ll just need to bring your own OpenAI API key.
<h3>✨ Key features</h3>
<ul>
<li>Automatic alt text on upload – set-and-forget accessibility.</li>
<li>Optional automatic image titles – improve SEO with descriptive titles.</li>
<li>One-click manual generation – “Generate Alt Text & Title” button in the Media Library.</li>
<li>Bulk update tool – batch-process existing images (five at a time) with a configurable pause between batches.</li>
<li>Prompt fine-tuning – supply site-wide context and optionally include the image file name.</li>
<li>Model selection – choose GPT-4o mini (default) or GPT 5 Mini/Nano (BETA).</li>
<li>Image size & detail control – choose the resolution and level of visual detail sent.</li>
<li>No extra servers – data flows only between your site and OpenAI; nothing is stored off-site.</li>
<li>Multilingual output – choose English (UK), English (US) or other popular languages. (English US is the default.)</li>
</ul>
<h3>🧭 Where to find the bulk tool</h3>
<ul>
<li>Tools → Bulk Alt Text Update</li>
<li>Media → Bulk Alt Text Update (shortcut that redirects to the Tools page)</li>
<li>Settings → Alt Text Generator includes a button linking straight to the bulk page</li>
</ul>
<h3>🧠 How it works</h3>
<ol>
<li>When an image is uploaded (or manually chosen), the plugin creates a temporary public URL for that image.</li>
<li>It sends the image – plus optional context such as the parent post title, your custom site context and the file name – to your selected OpenAI vision model.</li>
<li>OpenAI returns a concise description.
<ul>
<li>Alt text is stored in WordPress’ native <code>_wp_attachment_image_alt</code> field. </li>
<li>(Optional) The returned title is stored as the attachment post title.</li>
</ul>
</li>
<li>Nothing is cached or stored on OpenAI’s side; only the final strings live in your database.</li>
</ol>
<h3>Settings overview</h3>
<ul>
<li>OpenAI API Key – Required to connect to GPT-4o. </li>
<li>OpenAI Model – GPT-4o mini (default), GPT 5 Mini (BETA), or GPT 5 Nano (BETA). </li>
<li>Image Size to Send – Thumbnail, Medium, Large, or Full. </li>
<li>Image Detail Quality – ‘Low’ or ‘High’ (Low uses fewer tokens). </li>
<li>Bulk batch size – Number of images per batch (lower values reduce rate-limit risk). </li>
<li>Site Context – Optional free-form prompt guidance (brand voice, niche, etc.). </li>
<li>Send Image File Name – Include file name in the prompt for extra context. </li>
<li>Automatically Generate Title – Add descriptive titles alongside alt text. </li>
<li>Use full context for image titles – When enabled, title generation includes site context and file name (uses more tokens). </li>
<li>Bulk optimiser delay (seconds) – Pause between batches during bulk runs. </li>
<li>OpenAI request timeout (seconds) – Max wait time for OpenAI responses (10–120s) to reduce timeout failures on slower hosts. </li>
<li>Output Language – Default English (US). Choose English (UK) for British spellings or another popular language; outputs (alt text and titles) will be generated in the selected language.</li>
</ul>
