I was looking for this locking procedure. and found out the below code
works like no one can click on the image and save it other than
printscreen. this is best when a high resolution background image is
being used.
<html>
<head>
<script language="JavaScript1.2">
//Disable select-text script (IE4+, NS6+)- By Andy Scott
//Exclusive permission granted to Dynamic Drive to feature script
//Visit http://www.dynamicdrive.com for this script
function disableselect(e){
return false
}
function reEnable(){
return true
}
//if IE4+
document.onselectstart=new Function ("return false")
//if NS6
if (window.sidebar){
document.onmousedown=disableselect
document.onclick=reEnable
}
</script>
</head>

In any case, you''re deluding yourself if you think a solution like this is somehow "locking" your page - getting around this lock is trivially easy in most modern browsers. --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

The method can be defeated entirely by disabling JavaScript in the browser preferences. Even if JavaScript is not disabled your HTML source still exposes the public URI of the image. Using "View Source" then finding the <img> tag and copying the "src" URI into the browser address bar also defeats any protection JavaScript may attempt. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

However. If you have the skills or the money to buy them then you do have the same option as Flickr. Display your images from within a Flash app. This means that the source url for the image is harder to find - only harder mind you, wireshark or other similar tools will let you see this. But to be honest if you are putting images up on the web then someone will be able to work out a way of downloading them. The only solution to this that I can think of is perhaps having users log on to see the images and showing each user a customised image with a watermark that allows them to be identified when the image appears in the wild. Lot of processing to do that thought. But this does not stop people downloading them it just gives you someone to threaten with lawyers if the images appear somewhere else (and of course you have to start scanning the internet to see if your images have cropped up anywhere). Does this all sound expensive and not very effective? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: Re: Locking Images in HTML Files..can use it on ROR also
Thank you all,for your VALUABLE information. I didn''t find what i needed in this forum and many newbies are using this as a reference. That''s why i posted this. Why don''t u guys prove what u have written with some CODES, so that it becomes useful to OTHERS as well.

You showed some html and javascript and described what it achieves. Rails can of course generate any html and javascript that you like. Perhaps you should start again and explain what it is that you want to know. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Regarding your need for C0DEZZZZZ!!1!one!!eleven!!!!: Uninformed devs like you have been trying this "IM IN UR WEBPAGE DISABLING RITECLICK" routine since back in the days of Geocities. Guess what? It didn''t even work *then*. Would you like me to make a screencast that demonstrates how to disable JS in the browser to "prove" this? --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
