88000 2002-10-10 23:09:00 I am writing a website in CSS. I do not want to release my company logo as a file. I have used the following in the Page Head:

<Meta http-equiv="imagetoolbar" content="no">
but it is not working.

I have tried this in the Style Sheet:

:imagetoolbar {content:"no" }
but it doesn't work either.

Any ideas how it is supposed to be done?

TFYH

88001 2002-10-11 09:52:00 Hey man, you shouldn't rely on CSS for a website. You have use CSS as an accessory to HTML (or whatever) cos you know, compatibility issues, accesability. If you're a half decent web designer, you know these things. You know too that you cannot target your site for a particular res or browser. Thats a big nono.

You shouldn't have any problems using your company logo in a website, cos there is such a thing as copyright u know. If your comapnay is running, and registered, and already using the logo, then no probs. Sue anybody who tries to pinch it.

On the other hand, you can get the image watermarked, so it's unusable (theoretically)

Or you can also disable right click, but that's a compromise. 		JohnDoe (2202)

I'm not sure why you responded, given that you either insult my ability as a Web designer, or force me to admit that I am not "a half decent web designer". Which IS true, but at least I am trying to write in HTML, and not using FrontPage with its bloated script!

And the you off-handedly say I could disable the right click, which is obviously what I am trying to do but don't tell me how!

88003 2002-10-12 23:01:00 Hi Graham,

I did a wee search on google for your problem and found this link www.htmlgoodies.com
At least this one gives you some interesting options although it does point out that the code is specific to IE. 		Gorela (901)

88005 2002-10-12 23:53:00 whoa, the same reply like an hour apart (somethings wrong there, lol)

so yeah, my opinion of the whole 'disable right click' thing is if they REALLY want the image, its easy enough to obtain (eg, screen shot, read the source code by going View > Source code, and then going to the page that the image is located, etc, etc), there are ways of making the job more tedious by using css, but there isnt any way of making it 'uncachable' (well, as far as i know), and so far the best way i can think of is making a table where u intend to put the image, making a css class, and make the image a bg in this class, set the class on the table, and link the css to the page, instead of including it in the document (of course, my lingo is all created by me, a well seasoned beginner, who 'sort' of knows all this stuff :D), heres an example -

index.htm
<html>
<head>
<link href="index.css" rel="stylesheet" type="text/css">
</head>
<body>
<table width="75" height="75">
<tr>
<td class="logo"></td>
</tr>
</table></body>
</html>

index.css (in same directory)
.logo {
background-image: url(company_logo.gif);
}

of course, you could use this, as well as a popup which has no status bar, menu bar etc, and implement a 'disable right click' script too, but of course, all this would only make it difficult for IE users ?:|

88006 2002-10-13 00:23:00 You could also make a macromedia flash animation which just showed a static picture of your logo, but that is overkill if you ask me.

I wouldn't worry too much about it. The problem is, even with sal's method, all I would have to do is view the source code, download the style sheet, look where the image is located and viola!

In other words, you can make it difficult to copy using one of the methods above, but not impossible, and as sal says, unless you can stop the browser cahcing the picture, it will be sitting in the viewer's temp internet files anyway.
