原文外掛簡介
This plugin protects images on your WordPress site from being copied, saved, or captured through screenshots. It achieves this by implementing various protective measures via JavaScript, ensuring that your visual content remains secure from unauthorized use.
It also includes optional EXIF privacy tools to scan and remove privacy-sensitive metadata (such as GPS location) from images in your media library.
Plugin developed by TWK media.
Important Disclaimer
While this plugin implements various protection measures, it cannot guarantee 100% protection against all possible methods of image capture or copying. EXIF privacy cleanup cannot guarantee removal of every metadata field in every image format. Due to the nature of web browsers and operating systems, determined users may find ways to circumvent these protections. This plugin should be considered as a deterrent rather than an absolute solution. We do not provide any warranty or guarantee regarding the effectiveness of the protection measures.
Features

Layout-independent screenshot shortcut detection (Windows PrintScreen and Win+Shift+S, macOS Cmd+Shift+3/4/5, Linux PrintScreen) using key codes rather than key labels
Blurs protected media when the browser window loses focus or the tab is hidden (catches Snipping Tool, screenshot overlays, app switching)
Three selectable protection levels: Relaxed, Balanced, Strict (Settings > Image Protection)
Optional PrintScreen clipboard neutralization (Settings > Image Protection)
Optional screen-recording blur via the browser Screen Capture API (Settings > Image Protection)
Optional print/Save-as-PDF protection (Settings > Image Protection)

Optional EXIF privacy cleanup on upload (Settings > Image Protection)
Media library EXIF privacy scan and batch cleanup (Media > EXIF Privacy)
Compatible with all major browsers
What can and cannot be protected
No website can truly block an operating-system screenshot — browsers are sandboxed and have no access to system-level capture, and nobody can stop a photo taken with a second camera. This plugin is a strong deterrent, not an absolute block. Realistic coverage:
Desktop (Windows, macOS, Linux): best results. Detects most screenshot shortcuts, blurs on window focus loss (used by Snipping Tool and screenshot overlays), can neutralize the PrintScreen clipboard, can blur during in-browser screen recording, and can blank media in print output.
Mobile (Android, iPhone): only deterrents apply (no long-press save, no drag, no copy). Web pages cannot detect or block hardware-button screenshots or screen recording on phones.
Any device: a photo of the screen taken with another device cannot be prevented by any web-based tool.
Requirements
WordPress 5.0 or higher
PHP 7.4 or higher
JavaScript enabled in the browser
EXIF privacy features require the PHP EXIF extension; selective cleanup works best with the ImageMagick (imagick) PHP extension
