## Description

Simpli Auto Alt Text is a lightweight WordPress plugin that automatically generates
image alt text from filenames when images are uploaded to your website.

Adding meaningful alternative text to images is an important part of making website
content more accessible. However, manually entering alt text for every uploaded 
image can be time-consuming.

Simpli Auto Alt Text helps simplify this process by converting image filenames into
readable text and automatically saving the result in the WordPress Media Library.

The plugin works during the standard WordPress image upload process, requires no
additional configuration, and preserves existing non-empty alt text.

#### Key Features

 * **Automatic Alt Text Generation:** Generate alt text from image filenames during
   the WordPress media upload process.
 * **Filename Formatting:** Convert hyphens, underscores, and periods into spaces
   to make filenames easier to read.
 * **Readable Capitalization:** Automatically format generated text using title-
   case capitalization.
 * **Preserves Existing Alt Text:** Existing non-empty image alt text is never overwritten.
 * **Image-Only Processing:** Only image attachments are processed. Other media 
   files are ignored.
 * **No Configuration Required:** Activate the plugin and start uploading images
   without configuring additional settings.
 * **Lightweight Functionality:** Uses built-in WordPress functions and hooks without
   requiring external APIs.
 * **No Bulk Modifications:** Previously uploaded images remain unchanged.

#### How Simpli Auto Alt Text Works

When you upload an image, WordPress generates attachment metadata. Simpli Auto Alt
Text uses this process to generate readable alt text from the uploaded filename.

The plugin:

 1. Detects when WordPress generates image attachment metadata.
 2. Checks whether the attachment is an image.
 3. Checks whether the image already contains non-empty alt text.
 4. Extracts the image filename without its extension.
 5. Replaces hyphens, underscores, and periods with spaces.
 6. Normalizes spacing and capitalizes the resulting words.
 7. Saves the generated text in the standard WordPress image alt text field.

#### Example Filename Conversions

 * `summer-beach_vacation.2024.jpg` becomes `Summer Beach Vacation 2024`
 * `beautiful-mountain-view.png` becomes `Beautiful Mountain View`
 * `red_sports_car.jpg` becomes `Red Sports Car`
 * `my--photo___best.png` becomes `My Photo Best`

#### Who Can Use This Plugin?

Simpli Auto Alt Text can be useful for:

 * Bloggers who regularly upload images to their articles.
 * Website owners who want a simple starting point for image alt text.
 * Content creators who manage image-heavy websites.
 * WordPress developers who want automatic filename-based alt text generation.
 * Site administrators who want to reduce repetitive manual image metadata entry.

#### Works With the WordPress Media Library

The plugin uses the standard WordPress attachment metadata workflow and stores generated
alt text in the `_wp_attachment_image_alt` field.

Generated alt text can be viewed and manually edited through the WordPress Media
Library.

The plugin does not modify image files, change attachment titles or captions, or
process previously uploaded images.

#### Important Accessibility Note

Alt text generated from filenames is only a starting point. A filename does not 
always accurately describe an image or its purpose.

For better accessibility, review the generated text and adjust it to describe the
image in its actual context. Decorative images may require intentionally empty alt
text.

#### Simple and Lightweight

Simpli Auto Alt Text focuses on one task: automatically filling missing image alt
text from filenames when new images are uploaded.

No external AI services, API keys, additional accounts, or complex configuration
are required.

## Installation

 1. Upload the `simpli-auto-alt-text` folder to the `/wp-content/plugins/` directory,
    or install through the WordPress Plugins screen.
 2. Activate the plugin through the **Plugins** screen in WordPress.
 3. Upload an image — alt text is generated automatically from the filename.

## FAQ

### Does this overwrite existing alt text?

No. Alt text is only generated when the `_wp_attachment_image_alt` field is empty.

### Does this work for non-image attachments?

No. The plugin only processes image attachments.

### Does this run on existing media library items?

No. Alt text is set during the upload metadata generation process only.
