How to Generate Image Titles, Captions & Descriptions in WordPress Using AI (2026 Guide)

Managing image metadata has always been one of the most time-consuming parts of running a WordPress website. Whether you’re building a photography portfolio, travel blog, WooCommerce store, or business website, every image benefits from having a proper title, caption, alt text, and description.

The problem? Creating all that content manually for dozens—or even hundreds—of images takes hours.

That’s why we’re excited to introduce AI-powered Image Content Generation in Re Gallery.

With just a few clicks, Re Gallery can now analyze your images and automatically generate meaningful metadata for your entire gallery in seconds.

Why Image Metadata Matters

Image metadata serves several important purposes:

  • Improves accessibility through descriptive alt text
  • Helps search engines understand your images
  • Provides context to visitors
  • Makes media libraries easier to manage
  • Enhances gallery presentation and organization

Unfortunately, many WordPress websites either leave these fields empty or use generic content that provides little value.

Re Gallery’s new AI tools solve this problem automatically.

Generate Titles, Captions, Alt Text, and Descriptions

The new Generative AI feature can create:

Image Titles

Short, clean titles that describe the main subject of the image.

Example:

Before

  • IMG_2451.jpg

After

  • Mountain Lake Sunrise

Captions

Friendly captions that provide additional context and improve gallery presentation.

Example:

  • Crystal-clear mountain reflections captured during an early morning hike.

Alt Text

Accessibility-focused descriptions that help screen readers understand image content.

Example:

  • Snow-covered mountains reflected in a calm alpine lake

Descriptions

Short image descriptions suitable for blogs, portfolios, and media libraries.

Example:

  • A peaceful alpine lake surrounded by rugged mountain peaks under a clear blue sky.

Bulk Generate Content for Entire Galleries

The biggest advantage of the new feature is speed.

Instead of editing images one by one, Re Gallery can process an entire gallery at once.

Simply:

  1. Open your gallery
  2. Click AI Generate
  3. Choose which fields to generate
  4. Start generation

Within seconds, Re Gallery analyzes every image and fills the selected fields automatically.

Whether your gallery contains 10 images or 500 images, the workflow remains simple.

Generate Only Missing Content

Already have some metadata?

No problem.

You can choose how AI handles existing content:

Only Empty Fields

Generate content only for fields that are currently empty.

This option is perfect when you already have titles but need alt text and descriptions.

Overwrite Existing Content

Replace existing metadata with newly generated AI content.

Useful when older metadata is inaccurate, outdated, or inconsistent.

Image-Based AI Analysis

Unlike many tools that rely heavily on filenames or existing text, Re Gallery analyzes the actual image.

This means generated content is based primarily on what’s visible in the photo.

The result is:

  • More accurate metadata
  • Better accessibility descriptions
  • Cleaner captions
  • Improved consistency across galleries

New Dedicated Image Editing Experience

This release also introduces a completely improved image editing workflow.

Instead of jumping between different WordPress screens, you can now edit image metadata directly within a dedicated image editor.

The new interface makes it easy to:

  • Update titles
  • Edit captions
  • Improve alt text
  • Manage descriptions
  • Regenerate content with AI

All from a single, streamlined workspace.

For gallery owners managing large collections of images, this significantly speeds up content management.

Built for Modern WordPress Workflows

The new AI tools were designed with real WordPress users in mind:

Photographers

Generate metadata for hundreds of portfolio images in minutes.

Bloggers

Improve image SEO without manually writing descriptions.

Agencies

Save time when delivering client websites.

Ecommerce Stores

Enhance product galleries with better image content.

Content Creators

Spend less time on repetitive tasks and more time creating.

Smart Usage Controls

To give users flexibility and control, Re Gallery allows you to:

  • Select specific fields to generate
  • Process galleries in bulk
  • Generate only missing content
  • Regenerate content when needed
  • Review results before publishing

This ensures AI works as an assistant—not a replacement for your workflow.
