Avoid frames on your website
Some sites to keep the visitors on their own URL establish a link to your site posted inside a frame, i.e. one of HTML elements <object> (the only one still valid) <frame> ou <iframe>..
This is the case for example in search engines Google and Yahoo/Bing, during the search for images. They display a big image with your site in background for the first and on the bottom for the second. This is a hateful method, particularly from these rich web giants, which instead sending you traffic only facilitates the theft of your images.
/* To avoid frame in search engines: */
if (top != self)
top.location.href = location.href;
/* The code here */
