TWK Media

<p>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.</p>
<p>It also includes optional EXIF privacy tools to scan and remove privacy-sensitive metadata (such as GPS location) from images in your media library.</p>
<p>Plugin developed by <a href="https://thewebkitchen.co.uk/" rel="nofollow ugc">TWK media</a>.</p>
<h4>Important Disclaimer</h4>
<p>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.</p>
