Hi, I am new to website development. Have noticed that some images on my website have been copied and used on my competitor's site. The tag line descriptions have even been left intact! I saw somewhere that it is possible to prevent this copying but have no clue how to do this myself. By right-clicking on an image, the tagline message "stealing is wrong" would appear. Could one of you point me in the right direction? By the way, I am not suggesting that I have never done the same and copied an interesting image myself ... now I know what it feels like.
