portfolio hacking

@pierre22113559wzfn,

There is no reliable way to prevent thieves who are intent on taking online images from your site.  But there are few ways you can deter them:  

• Watermark images heavily with your URL.
• Use low res images online.

The other option is to purchase digital barcoding service to protect your copyright.  Digital watermarks are not visible to humans and tracks where images are being used.  There is a Digimarc plugin available for Photoshop.

Hope that helps.
