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>

Image Alt Sync scans selected posts and updates any <code><img></code> tags found in the post content that reference media items (class <code>wp-image-###</code>), and replaces their <code>alt</code> attributes with the attachment’s <code>_wp_attachment_image_alt</code> value: 
– If the image is in the Media Library, it prefers the attachment’s Alt Text. 
– If no attachment alt is set, it falls back to the image filename (without extension) or the post title (configurable in the UI). 
– Optionally skip images that aren’t found in the Media Library. 
– Optionally restrict by image file extensions (e.g. <code>jpg,webp</code>).
Run in dry run first to see exactly what would change. The log shows each post processed and any per-image alt changes.
Highlights 
– Processes per post in batches with a customizable delay (default 100 posts, 1s). 
– Filter by post status and date range (quick buttons: Today, Yesterday, Last week, Last month, YTD, All). 
– Validate that “Date after” ≤ “Date before”. 
– Limit by Post ID range with buttons to auto-fill lowest and highest post IDs. 
– Skip posts without <code><img></code> (optional). 
– Exclude image extensions (comma-separated, e.g. <code>.svg,.gif</code>). 
– Dry run (browser & WP-CLI) shows clickable post IDs, post titles, filenames, and detailed old → new alt replacements. 
– Only processes posts that have at least one image attachment.
For more details you can send mail with your suggestions, recommendation to dufour_l@hotmail.com
<h3>Usage</h3>
<ol>
<li>Choose your filters (date range, min/max post ID, or “Apply to all posts”).</li>
<li>Set Batch size and optional Delay between batches to throttle load.</li>
<li>Choose a Date Range, or click a shortcut button (autofills Date after/Date before).</li>
<li>(Optional) Enter Lowest/Highest Post ID or click the quick-fill buttons.</li>
<li>(Optional) Check Skip posts without <code><img></code>.</li>
<li>(Optional) Enter Exclude extensions like <code>.svg,.gif</code>.</li>
<li>Optionally enable Dry run to preview changes without saving.</li>
<li>Click Start. Progress and detailed per-post changes appear in the log.</li>
<li>If needed, click Stop to pause after the current batch finishes.</li>
</ol>
Tips 
– Use the “Lowest ID” and “Highest ID” buttons to auto-fill the ID range. 
– Use the extension filter (e.g. <code>jpg, jpeg, png, webp</code>) to target specific image types. 
– Check “Skip images not in media library” to avoid external or missing files.
