JavaScript - catch right-button-clicks and do something else with them. (user can turn off JavaScript) (many scripts of this sort are vulnerable to: press and hold left button, click right button, release left button) 2. Put the image as a table background, then put a transparent .gif over it - someone right-click-and-save'ing will get themselves a transparent .gif (use can look at the source and call the image directly, or pick it out of the browser cache) 3. Put a placeholder picture in, then use JavaScript to dynamically swap your actual image so it doesn't show up in the HTML source (user can trace the JavaScript or write themselves a script to return the current image URL) (users without JavaScript are severely peeved) 4. Use an applet or plug-in to display a non-clickable image (User can view source then call image directly). (People trying to print out your page will hate you). 5. Use an applet or plug-in to display a non-clickable image stored in some non-standard format. (Hackers will enjoy munching on your plug-in; everyone else will use a screen-capture utility). Basically, (a) if a user can see it they can steal it, and (b) trying to prevent this just ticks people off.
