原文外掛簡介
Focalio serves cropped, format-converted image variants on demand via signed URLs — no more pre-generated intermediate sizes filling up your uploads directory. Editors pick a focal point per image so crops always keep the subject in frame.
Features:
On-demand image cropping via signed URLs
WebP or AVIF output for all uploads
Focal-point picker in the media library and the block editor
Non-destructive rotate and flip, applied to every rendition
LQIP (Low Quality Image Placeholder) support
Settings for image quality, output format and maximum width
Presets, as many as you need: edited on the Presets tab, each with its own quality and LQIP, or registered in code with glide_register_preset()
Attention / entropy / center crop fallback for images without a manual focal point
Cached images are served before the rest of WordPress loads
Presets also appear as image sizes, so the media library, Advanced Custom Fields, widgets and page builders can pick them by name
Optional: skip writing intermediate image sizes to disk on upload
Turn off the WordPress image sizes your site does not use
A Cache tab: how big the image cache is, and a button to clear it. A weekly cleanup drops renders that are no longer used
WP-CLI commands for the cache and the crop fallback
WooCommerce product images go through Focalio too, and its cropped sizes follow the focal point
Multisite: activate it for the whole network; deleting it cleans up every site
Focalio Pro is a separate add-on for agencies and editorial teams, not included in this plugin. It adds:
Control: focal-point zoom, a straighten ruler that levels a tilted photo by up to 45°, a live crop preview, a hand-made crop per ratio where the focal point is not enough, and a watermark
Performance: AVIF with a WebP fallback in a picture element, and a cache warm-up that renders images before the first visitor asks for them
Workflow: face detection that puts the focal point on the people in a photo, bulk actions in the media library, and tools to manage every site of a multisite network
WooCommerce: the shop grid of a block theme cut on the focal point at the store’s ratio, and one ratio for every photo on a product page
External services
Focalio includes the Freemius SDK (https://freemius.com), which handles the opt-in to share usage data and the licenses of the Focalio Pro add-on. Nothing is sent to Freemius unless you opt in; images are always processed on your own server.
What is sent, and when:
When you opt in (on the screen shown after activation): your WordPress user’s first and last name and email address; the site’s homepage URL and title, WordPress and PHP versions and site language; the Focalio and SDK versions, and whether Focalio is active. The list of plugins and themes (names, slugs, versions, active or not) only when you leave that option on.
After opting in: changes to that information, and when Focalio is activated, deactivated or uninstalled. If you fill in the optional form on deactivation, the reason you give.
You can opt out at any time with the “Opt Out” link under Focalio on the Plugins screen. Focalio works the same either way.
