Hotlink2Watermark is a plugin which allow you to display a watermark within each images being ‘hotlinked’ from your website. 
An hotlinked image is an image hosted on your website but displayed on another website by an unscrupulous webmaster 
This overload the bandwith of your website without bringing any visitor. 
This plugin transform this inconvenience into advantage by allowing you to display a link to your image on these image.
Features:
<ul>
<li>Add a watermark to all hotlinked image from your blog, on the fly!</li>
<li>All generated pictures are buffered into a directory for optimised use</li>
<li>Choice of watermark: can be a text or a picture</li>
<li>.htaccess update if needed</li>
<li>Can save all the referers (website which steal your bandwidh) on a csv file</li>
<li>Create/delete the buffer directory on install/uninstall of the plugin, for non-wasted disk space</li>
<li>NEW You can choose between 4 fonts for the watermark, and select text and (optional) shadow colors</li>
</ul>
Update Notice: 
As there are several new features, the buffered image in the cache directory must be regenerated, with different name. 
So, you should delete the whole content of the directory “cache” in the directory “hotlink2watermark” to gain some space, as the files in this directory won’t be used anymore.
