<p>You can simply apply a custom watermark to all your images, which are in your uploads folder.<br />
This plugin renders the watermark on-demand on your images, i.e. no data is altered and the watermark is also rendered on already uploaded images.</p>
<p>You can find the settings under: <strong>Settings/Dynamic Watermark</strong></p>
<p>Main Features:</p>
<ul>
<li>Custom watermark</li>
<li>Transparency is supported (alpha channel)</li>
<li>Enable/disable watermarking</li>
<li>No images are altered</li>
<li>Watermark already uploaded images</li>
</ul>
<p>Here are some requirements to run the plugin (most of the time no problem):</p>
<ul>
<li>Mod_rewrite module installed</li>
<li>Write permission for uploads folder</li>
</ul>
