<p>WP Strip Image Metadata is a privacy focused WordPress plugin that helps in removing potentially sensitive metadata from your uploaded images. It strips image metadata on upload or via bulk action, and view image EXIF data.</p>
<p>This Plugin is based on the Plugin “WP Strip Image Metadata” from the WordPress.org plugin repository here: https://wordpress.org/plugins/wp-strip-image-metadata/</p>
<p>This Plugin extends the Functionality of “WP Strip Image Metadata” with the following Functions:</p>
<h4>Extended Functionality</h4>
<ul>
<li>Handle AVIF and WEBP-Images, too.</li>
<li>set / add / change Copyright, Artist or Credit Information in JPG and WEBP images Files.</li>
<li>Set an upper Size Limit for the Stripping. All Files with Width greater than Size Limit won’t be stripped.</li>
<li>Show some more Information in the Image Edit Panel</li>
<li>Set a Minimum version for Imagick (3.4.4) and Gmagick (2.0.5) to handle files at all. Gmagick is still limited in functionality.</li>
</ul>
<h4>Preparation of Copyright Template Files</h4>
<p>Both Imagick and Gmagick do not allow to set EXIF-Metadata directly. The author of this plugin does not know an Open Source PHP or WordPress Function with appropriate License to set metadata in an Image File. So a Template File is used that has to be prepared by the user. It’s only possible to use one template File for<br />
one Artist, only! The Plugin uses one Template File for the whole site. So, if you are on a Multi-User-Site this Plugin is not for you.</p>
<ol>
<li>Prepare a JPG, WEBP and AVIF File with very small size, e.g. 100×100 or so. Image dimensions do not matter, here.</li>
<li>
<p>Strip all Metadata with exiftool (current version writes avif and webp, too):</p>
<p><code>exiftool.exe -all= ./yourfile.jpg -o copyright.jpg<br />
exiftool.exe -all= ./anotherfile.webp -o copyright.webp<br />
exiftool.exe -all= ./aviffile.jpg -o copyright.avif</code></p>
</li>
<li>
<p>Add the Copyright (or other) EXIF-Metadata you prefer with Exiftool like so</p>
<p><code>exiftool.exe -copyright="Copyright by User of the Plugin and Site" ./copyright.jpg<br />
exiftool.exe -artist="User of the Plugin and Site" ./copyright.jpg</code></p>
</li>
</ol>
<p>The other functionality of the Plugin was not changed so the original Readme follows herafter.</p>
<h4>Original Description</h4>
<p>Strip image metadata on upload or via bulk action, and view image EXIF data.<br />
WP Strip Image Metadata is a privacy focused WordPress plugin that helps in removing potentially sensitive metadata from your uploaded images.</p>
<h4>What is image metadata?</h4>
<p>Image metadata is extra information embedded in image files. This information is stored in a variety of formats and contains items like the model of the camera that took a photo.<br />
However, image metadata may also contain identifying information such as the GPS location coordinates of an image taken with a smartphone for example.<br />
This plugin provides an easy enabled/disabled setting so you can make the call on when image metadata should be removed.<br />
<strong>Note</strong>: this plugin requires the “Imagick” or “Gmagick” PHP extension to function.</p>
