## 説明

LiteImage is a lightweight, developer-friendly WordPress plugin that optimizes images
using dynamic thumbnail generation, WebP support, and accessibility enhancements.

over responsive image rendering and disk space management.

   function

 * Responsive Images: Serve the right image for the right device with media queries
 * Mobile-Specific Images: Serve a dedicated mobile MOBILE-specific image for viewports
   under 768px
 * Accessibility: Add alt, aria-label, and other HTML attributes
 * Clean Thumbnails: Delete LiteImage or WordPress-generated thumbnails from Toolsower
 * Debug Logging: Track plugin activity when logging is enabled

## 変更履歴

#### 3.3.3

 * Added: Settings for output quality (60–100): WebP when WebP thumbnails are enabled;
   separate JPEG/lossy and PNG compression when serving original formats.
 * Added: Admin UI toggles quality fields based on the “Generate WebP” option; PNG
   uses zlib/Imagick compression strength (lossless pixels).
 * Fixed: PNG encoding compatible with PHP 8+ (removed invalid extra argument to
   Intervention Image PNG encoder).
 * Fixed: Smart compression reference PNG creation uses a proper image clone.

#### 3.3.2

 * Added: Support for conversion at original size — when `thumb` is `'full'` or `[
   0, 0]`, images are converted (WebP and original format) without resizing.
 * Added: In `liteimage_downsize()`, size `[0, 0]` now returns the original image
   dimensions.
 * Added: In `get_thumb_size()`, support for `'full'` and `[0, 0]` with correct `
   size_name` in format `liteimage-{width}x{height}`.
 * Fixed: Safe reading of `width`/`height` from attachment metadata in `liteimage_downsize()`
   when keys are missing.

#### 3.3.1

 * Fixed: Thumbnail filename conflicts when multiple images share the same filename.
   Added attachment ID to thumbnail filenames to ensure uniqueness.
 * Fixed: Format changed from `{filename}-{size_name}.{ext}` to `{filename}-{attachment_id}-{
   size_name}.{ext}` for all thumbnail variants (WebP, original format, and retina
   @2x versions).

#### 3.3.0

 * Added: Gutenberg block **LiteImage Image** with full responsive controls for 
   desktop/mobile sources, breakpoints, and HTML attributes.
 * Added: PHPUnit smoke test covering block attribute sanitization.
 * Added: Automatic 2x retina variants for all generated LiteImage sizes, including
   Gutenberg block output.
 * Changed: Refreshed plugin icon to match the new brand palette.
 * Changed: Updated documentation with block usage instructions and retina guidance.

#### 3.2.1

 * Fixed: Unescaped output in admin tab navigation (WordPress.org Plugin Check compliance)
 * Fixed: Removed deprecated load_plugin_textdomain() call (WordPress auto-loads
   translations since 4.6)

   6.8, Requires at least: 5.8)
