| Ah... The old how do I protect an image on the web topic! <*sigh*> Never
| seems to grow old no matter how many times it gets asked...
|
| Okay, first off, I do not recommend disabling the right-click menu. As a
| tool to protect images, it is useless. The images are already
| transferred to the user's machine so they are easy to locate. All it
| will do is annoy visitors to your site who use the right-click menu for
| bookmarking a site, printing something, etc.
|
| Overlaying a transparent GIF over the top of an image is of more use, I
| think, than disabling the right-click menu. However, generating the code
| to do that for a lot of images can be very time consuming.
|
| Nor do I recommend image-slicing as a way of image protection. Doing
| this doesn't stop anyone from using screen capture tools. So again, I
| feel that is a wasted effort.
|
| A better approach is to start by using a lower-quality image to begin
| with, and include visible watermarks inside it. JPG files will reduce in
| quality as they are compressed, so this will reduce bandwidth
| consumption too. Just how much should you compress an image? This will
| vary quite a bit depending on the image. Use graphic tools that allow
| for an interactive view as you adjust this setting.
|
| When creating a visible watermark, use the tools within your program to
| make it semi-transparent. Emboss effects often work well, if your
| program supports this. The idea is to have something that can easily be
| seen, yet is difficult to remove from the image. Here are a couple of
| online tutorials on this topic:

|
| There are other techniques that can be used which involve the use of
| plug-ins and encrypted files. But, those are not cheap! Another concern
| that goes along with this topic is how to prevent hotlinking. (Someone
| linking to files located on your site, and claiming them as their own.)
| As with anything else, you're going to have to decide just how much
| effort and money you want to put into this. I might also suggest
| speaking to a professional developer if any of the suggestions I've made
| are beyond your capabilities.
