It seems like everyone else who answered here didn’t read the question.

Yes, it is possible to remove these icons. Just put the following in the <head> of your document.

<meta http-equiv="imagetoolbar" content="no" />

As mentioned in the other answers, users will still be able to get the images if they really want to, no matter how hard you try to prevent it. If you don’t want the images to be copied, you shouldn’t use them on a website.

It sounds like you're talking about the Image Toolbar in Internet Explorer. You can disable it with this code:

<html>
<head>
<meta http-equiv="imagetoolbar" content="no" />
</head>

</html>

Or, directly applied to an image:

<img src="test.gif" galleryimg="no" />

No it's not possible. The user can see the image in the browser and thus the browser (and the user) has a copy. You can try and restrict that with nasty (and ill-advised) right-click JS hacks and the like but ultimately if you send something to someone to see or read, what they do with it is beyond your control when you don't control the device they're using.

You can only do so much to prevent some users. To be near 100% foolproof, it's probably impossible. Even if you packaged the images in say, flash, java applet, it doesn't stop users from doing screencapture too.

There are few passive alternatives, e.g. using watermarks, putting up discalimers/warnings.

Here are some related SO posts:

if you are using Apache server, you can disable accessing the image through absolute url
the images can be access only with relative url with this htaccess code :

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yourdomain.com [NC]
RewriteRule \.(jpg|jpeg|png|gif)$ - [NC,F,L]

in addition, disable the right click context using JavaScript, and add a watermark to protect the copy rights
this will reduce the chance of saving the images

Prevent users from downloading images it's a waste of time because even if they cannot download the image, they always could do an screenshot :-(

You cannot prevent the downloading of your images. Just by viewing them, the browser caches them.

If the browser can get it, then the user can somehow get it.

You could investigate using an HTML5 canvas or even (gasp) pixelized tables to render client-side.

.show_IMAGE
{
   background-position : 0 -100px;
   background-image : url('/images/flower.png');
   background-repeat : no-repeat;width:50px;height:50px;
}

and add this class to DIV
