AquaMark is a full-featured, professional solution for applying image watermarks to your media uploads. 
Built with a modern, robust architecture, it provides extensive control over the appearance and placement of your watermark, ensuring your brand is consistently represented across your site. 
The plugin automatically uses the best available image processing library on your server (Imagick for quality, GD for compatibility) to deliver excellent results.
<h4>Core Features</h4>
<ul>
<li>Selectable Watermark Image: Choose any image from your Media Library to use as a watermark.</li>
<li>Precise Positioning: Place your watermark in any one of nine grid positions (top-left, middle-center, bottom-right, etc.).</li>
<li>Fine-Tuned Offset: Adjust the watermark’s final position with pixel (px) or percentage (%) based X and Y offsets.</li>
<li>Flexible Sizing: Control the watermark’s size with pixel (px) or percentage (%) based width and height. Supports auto-scaling.</li>
<li>Opacity Control: Set the transparency of your watermark from 0% (fully transparent) to 100% (fully opaque).</li>
<li>Advanced Blend Modes: Go beyond simple overlays with Photoshop-like blend modes, including Normal, Multiply, Screen, and Overlay.</li>
<li>Target Specific Image Sizes: Choose exactly which registered image sizes should receive the watermark (e.g., thumbnail, medium, large).</li>
<li>Image Driver Selection: Automatically uses the best image library available (Imagick or GD), with a manual override option for advanced users.</li>
<li>Destructive Action Warning: The plugin warns you if you choose to apply the watermark to the ‘full’ size image, as this is a permanent, destructive action.</li>
<li>Regenerate Watermarks: Easily apply new settings to existing images via a “Regenerate Watermarks” bulk action in the Media Library.</li>
<li>Remove Watermarks: Remove watermarks from existing images via a “Remove Watermarks” bulk action in the Media Library.</li>
<li>Developer Friendly: Includes WordPress actions and filters for programmatic extension and customization.</li>
<li>Modern & Conflict-Free: Built with modern PHP and scoped dependencies to prevent conflicts with other plugins.</li>
</ul>
<h3>Developer Documentation</h3>
