You must have noticed that Orkut has disabled right click on images in orkut albums. This means you can’t save images from an orkut album. There are a couple of tricks throug which you can still save images. These tricks can be used to save images from many other sites with right click disabled.
The simplest way is to drag the image to the address bar. You can also drag it to a new tab or to the new tab area to open in a separate tab.
