This plugin allows you to add a watermark images on all images that were uploaded in your wordpress. The watermark is generated on-the-fly and cached for faster access.
To see the plugin in action, select “Add watermark to all images”, chose a watermark image and and submit the settings page. You should then see the watermark appearing on your site. You might need to reload the page (F5 in most browsers) to bypass the browser cache.
The plugin does not change your source images. To disable all watermarks, simply disable the plugin, and everything is back to normal.
If you encounter errors (especially syntax errors), check your PHP version. It should be at least 7.0. This plugin requires Apache and mod_rewrite.

Watermark RELOADED is a lightweight WordPress image watermark plugin that automatically adds a customizable text watermark to images when you upload them to your Media Library.
Use it to:
<ul>
<li>Protect your work from unauthorized reuse</li>
<li>Brand images with your site name, URL, or copyright notice</li>
<li>Keep control of your visual content with a simple, set-and-forget solution</li>
</ul>
You can:
<ul>
<li>Choose which image sizes to watermark: thumbnail, medium, large, full size</li>
<li>Customize text watermark font and color</li>
<li>Precisely control watermark position (corners, edges or centered) on the image</li>
<li>Preview your watermark before saving settings so you know exactly how it will look</li>
</ul>
The plugin adds:
<ul>
<li>A dedicated Watermark RELOADED settings page where you configure your watermark and see a live preview</li>
<li>A WordPress Dashboard widget that shows your current watermark settings and a preview of the watermark directly on the main Dashboard screen</li>
</ul>
<h3>Key Features</h3>
<ul>
<li>Automatic watermark on upload – newly uploaded images are watermarked immediately</li>
<li>Text watermarking – add copyright text, site name or any custom message</li>
<li>Custom fonts – upload your own TTF fonts to use for the watermark</li>
<li>Color picker integration – choose any text color for your watermark</li>
<li>Per-size control – enable watermarking only on selected image sizes</li>
<li>Live settings preview – see how your watermark text, color and position look in the plugin settings before they are applied to new uploads</li>
<li>Dashboard widget – quickly review enabled sizes, position, offset and a preview from the WordPress Dashboard</li>
<li>Simple, focused UI – no unnecessary settings, just what you need to protect your images</li>
</ul>
<h3>How it works</h3>
<ol>
<li>You configure your watermark text, font, color, and position in Settings → Watermark Reloaded.</li>
<li>You choose which image sizes should receive the watermark.</li>
<li>When you upload a new image through the Media Library or post editor, Watermark RELOADED automatically applies the text watermark to the selected sizes.</li>
</ol>
Existing images in your Media Library are not modified – only new uploads are processed.
<h3>Requirements</h3>
To generate watermarks, your server must support:
<ul>
<li>PHP 5.3+</li>
<li>GD extension for PHP</li>
<li>FreeType Library (for rendering text)</li>
</ul>
If any of these are missing, the plugin will show an error message so you can contact your hosting provider.
<h3>Planned improvements</h3>
The following ideas are on the to-do list and may be implemented in future updates:
<ul>
<li>Additional bug fixes and compatibility adjustments</li>
<li>Smarter handling of small images where the watermark might overflow</li>
<li>Support for watermarking additional custom image sizes added by other plugins/themes</li>
<li>Image-size aware watermarks and more flexible positioning options</li>
</ul>
