Protect an imageTag(s): HTML/CSS
You can make it a little bit harder by placing over an image (to be protected) a transparent GIF.
<span style=
"background-image:
url('images/realhowto.gif'); background-repeat: no-repeat;">
<img src="images/transparent.gif" width="16" height=16"
border="0" alt="RealHowTo">
</span>
