Actually I am trying to protect my images. I know there are numerous ways to get images but to the maximum possible extent for a layman I want to use some Java scripts e.g. disabling print screen and right click etc. but fire fox and other browsers doesn't recognise them that's why am trying that user should be able to see my images only and only in MS internet explorer and not in other browser

What you're trying to do is fundamentally at odds with how the web works. If it is acceptable that some people can't see the images because they use a particular browser, then I concur with the advice given to you elsewhere: don't show them at all.
Farakh, Firstly, why are you trying to protect the images? Do they contain secure information that requires a login? Do they cost money? If it's either of these, you can protect the images by only allowing logged in users to see them. Yes, they can save them. You have to expect logged in users to have some sense of responsibility. And if you are selling them, you can embed user specific information in the image itself to see who is provide unauthorized copies.
I'm also curious why you don't want the user printing the page. That's not distributing it to others electronically. This is impossible to block anyway (you can just do a print screen.)
but to the maximum possible extent for a layman
I don't understand why. A person motivated to steal your data is more likely to be technical. Or at least have someone technical to ask. And more and more people are technical enough to get around these days.
My point is that if you make the site hard to use, a couple things might happen: 1) Firefox/Opera/Safari users will go elsewhere - I went to a different anti-virus vendor because I couldn't renew in Firefox and their response was to "just use IE". 2) They will go around your restrictions - I showed my mother the keyboard shortcuts to print a page for a site that didn't want you printing things. She wanted to print her receipt for a transaction - a perfectly valid thing to do!
That post was longer than I expected. My main point was to share the business reason you don't want people saving/printing the images. This is the real problem you want to solve and might have a technical answer.

Actually I am working for an international wedding card designer company who are working hard around the year and producing 200 wedding cards that costs approximately one 0.5 million dollars but when we are putting our cards on the website the cheaters copying these designs and start selling just for nothing and we got nothing except loss
and if we are not publicizing these cards then how the peoples will know about the new cards
In this scenario what you recommend?
Thanks & best regards

Farakh, Knowing the business driver helps. Most importantly, no technological measure can prevent people from using your design. If someone can see it, they can copy the ideas on paper let alone downloading a digital copy.
How about a business driven solution: show one or two designs as leads, ask people to contact you for details, etc.
Another idea is to see what your competitors do to protect their intellectual property. A quick search showed the first wedding card site I found that shows samples in both Flash and image format.
One tactic you might use is to emboss the images with a copyright notice that still gives the viewer an idea of what the image is like, but makes it difficult for even someone well-versed with Photoshop to eradicate.
