详情介绍:
ODR Image Optimizer is a professional-grade performance suite built on SOLID principles. Unlike monolithic optimization plugins, ODR focuses on the critical rendering path to eliminate resource discovery delays.
Designed to hit a 100/100 Lighthouse score on mobile under standard configurations. By decoupling image processing from delivery policy, the plugin reduces Largest Contentful Paint (LCP) by optimizing how the browser prioritizes assets.
Performance Results (reference test site, mobile Lighthouse):
- Largest Contentful Paint (LCP): 1.4s (↓ 1.0s improvement)
- First Contentful Paint (FCP): 1.0s
- Total Blocking Time (TBT): 0ms
- Cumulative Layout Shift (CLS): 0 Real-world numbers will vary based on theme, hosting, and content.
安装:
- Upload the
odr-image-optimizerfolder to the/wp-content/plugins/directory. - Activate the plugin through the 'Plugins' menu in WordPress.
- Open the new ODR Image Optimizer entry in the WordPress admin sidebar and configure your toggles under the Settings submenu.
常见问题:
Will this slow down my site?
No. ODR Image Optimizer adds minimal overhead (~2KB to the page) and removes competing resources. The net result is faster perceived performance and better Lighthouse scores.
Can I disable specific optimizations?
Yes. Open ODR Image Optimizer → Settings in the WordPress admin sidebar. From there you can:
- Pick a compression level (low / medium / high)
- Enable or disable WebP conversion
- Choose a lazy-load strategy (native / hybrid / off)
- Toggle auto-optimize on upload
- Toggle "Preload Theme Fonts"
- Toggle "Kill Bloat" (removes the Interactivity API and Emoji scripts)
- Toggle "Inline Critical CSS"
Is this compatible with other image plugins?
ODR works best as the only image optimization plugin. Having multiple optimization plugins can cause conflicts. Disable any other image optimization plugins before activating ODR.
What WordPress versions are supported?
WordPress 6.0+. Requires PHP 8.1+.
Do I need to re-optimize existing images?
No. ODR works on all images, new and existing. Simply activate and the plugin handles optimization automatically.
更新日志:
1.0.12
- Docs: Added directory listing assets — icon, banner (772x250 + 1544x500 retina), and a desktop Lighthouse audit screenshot.
- Docs: Renamed "Cleanup Service" to "Kill Bloat" in the Features list to match the actual toggle name in the settings UI.
- Docs: Softened the "100/100 Lighthouse" claim in the Description so it reads as a design goal rather than a per-install guarantee.
- Docs: Listing copy accuracy pass — admin menu location, FAQ toggle list, missing 1.0.1 entry, 1.0.8 upgrade notice, hedged performance numbers.
- CI: Deploy workflow resolves the SVN tag from
Stable tag:inreadme.txtinstead of inferring from the branch ref.
- Fix: Move image backups out of the plugin folder. Backups now live under
wp-content/uploads/odr-image-optimizer/backups/<relative path>/instead of a.backupsdirectory next to each media file, per WordPress.org plugin guidelines. Reverts of images optimized on older versions still read from the legacy location as a one-time fallback. - Chore: Remove non-permitted distribution files (development sed script, build-artifact zips) from the plugin root.
- Chore: Add
uninstall.phpto remove the plugin's options and backup folder on uninstall.
- Fix: Move phpcs:ignore for InterpolatedNotPrepared to the SQL string lines; use phpcs:disable/enable blocks for multi-line queries (class-database, WebpDelivery, DatabaseRepository)
- Fix: Remove inline comment text before phpcs:ignore on NonPrefixedConstantFound (odr-image-optimizer.php line 36)
- Fix: Add phpcs:ignore for confirmed false positives (ExceptionNotEscaped, NonPrefixedConstant/HookName, DirectDatabaseQuery, InterpolatedNotPrepared, is_writable/chmod in background processing context)
- Fix: Add ABSPATH direct-access guard to all index.php stub files
- Fix: Replace unlink() with wp_delete_file() (WebpConverter, class-optimizer)
- Fix: Replace date() with gmdate() (class-database, DatabaseRepository)
- Fix: Gate error_log() calls behind WP_DEBUG check
- Fix: Sanitize $_SERVER['HTTP_ACCEPT'] via wp_unslash/sanitize_text_field
- Fix: Reduce readme.txt tags to 5; add required short description
- Fix: Align sanitize_settings() whitelist with registered fields (add remove_emoji, font_swap; remove stale remove_bloat key)
- Fix: Escape WebP URL with esc_url() in the_content filter callback to prevent potential XSS
- Fix: Move Performance Toggles admin page under plugin nav menu instead of wp-admin Settings
- Fix: Accept array $size in add_webp_picture_element() and render_picture_element() to match WordPress core behavior and prevent TypeError on WooCommerce order emails
- Fix: Achieve Lighthouse 100/100 with complete WordPress.org compliance
- Fix: Navigation script deferral now works on-demand (click/touch interaction)
- Fix: Settings toggle now fully controls all feature behaviors
- Refactor: Moved navigation deferral from mu-plugin to main plugin service
- Refactor: Complete SOLID principles implementation with DI Container
- Refactor: All WordPress hooks prefixed with
odr_for global namespace safety - Docs: Enhanced documentation for WordPress.org submission
- Polish: Enhanced plugin header metadata for WordPress.org consistency (description, PHP requirement aligned to 8.1, refreshed tags, Plugin URI now points to GitHub).
- Initial release.
- Added Priority Service for LCP optimization.
- Added Cleanup Service for bandwidth reclamation.
- Consolidated settings into a unified dashboard.
- Implemented SOLID architecture for maintainability.
- Added comprehensive case study documentation.
- Full internationalization support (i18n ready).
- Security audit complete: nonce verification, capability checks, late escaping.
- PHPStan Level Max compliance (strict types throughout).
- PSR-12 formatting enforced via CI/CD.
