Photos and Images

[Ship called Dignity]

Malky - I sent an e-mail to you about this via your campbeltownloch site but I'll post on here to see if anyone knows in general.

I am adding a new Photo Album to the site but I am keen to protect the images I am going to post.

I thought I had this sussed and added a bit of html which doesn't allow browsers to right click on the images and save to their PC.

However, I have since noticed - and this may be a feature only on XP(?) - if you hover your mouse on the top left corner of any image you are able to save the image to your PC.(!) You can also print it etc.

So how do you get round this? Or do you just have to hope that people respect your copyright?

If the files are embedded within a site restrictions can be placed on them with regards to downloads etc from the html - similar to the disabled right-click.

Here might help.


You could also watermark the pics to make it clear they are yours.

Hi Davie,

Campbeltownloch email goes to Russell but eventually arrives at me if he wants me to do something

I also disabled right-click on the photos on the Campbeltownloch site with a simple script but you can still copy the photos via the edit menu in the browser

Of course, IE 6 then arrived on the scene with it's helpful little image toolbar that pops up and allows you to copy, print etc with ease

To be honest, there is no real way to protect images because as soon as anyone visits your page, all the images on it (along with the source code) are cached in your Temporary Internet Files and fully accessible. They could also do a screen capture if they were so inclined. Best you can do is make things difficult.

You've already disabled right-click so to disable the image toolbar in IE6 you have 2 options. Use either one of the following, whichever is easiest for your site.

1. Insert the following meta tag in the head of your document:

<META HTTP-EQUIV="imagetoolbar" CONTENT="no">

2. Use the galleryimg attribute in your image tag.

<img src=”myimage.jpg” width="210" height="250" GALLERYIMG="no" >

I believe you can also encrypt your code but I don't know too much about that. A Google search might help.

Last thing is digital copyrighting. All the images on the Campbeltownloch site are fixed up and put together by Russell who digitally signs them using Photoshop. You can't see it when viewing the image as its embedded in it.

Hope that helps

Yes embedding the owner info - but an obvious watermark usually is a nice deterent.

Its not just IE6 it does the same on firefox???

[Malky]

I use firefox and it doesn't have that feature Does it?

Aye - your right - it was late night and I was sure I checked this on Firefox - must have been IE again! That is why I posted above the question about it being XP! Doh!

Are Microsoft stupid or something? Don't answer that question!

Anyway, cheers for that.

Am sure it does via one of the many plugins available.

But firefox allows you to right click! Regardless of your warning message!

Bandits!

Hrm - I have visited a few sites where right clicks have been disabled from Firefox.

[Malky]

Haven't tried this myself Davie, but it's supposed to work with Firefox.

Worth a try eh Copy and Paste........

Code: Select all

<script language=JavaScript>
<!--

var message="Function Disabled!";

///////////////////////////////////
function clickIE4(){
if (event.button==2){
alert(message);
return false;
}
}

function clickNS4(e){
if (document.layers||document.getElementById&&!document.all){
if (e.which==2||e.which==3){
alert(message);
return false;
}
}
}

if (document.layers){
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=clickNS4;
}
else if (document.all&&!document.getElementById){
document.onmousedown=clickIE4;
}

document.oncontextmenu=new Function("alert(message);return false")

// -->
</script>

Cheers folks - that is the one I tried.

As I said it means you can't right click but anyone with IE 6 can obviously just hover over the image and save it.

It isn't a major problem as I could add watermarks - but as you well know that takes time!

Cheers again

Have you tried the meta tag and the galleryimg tag I mentioned above to disable the image toolbar?

Malky

[Ship called Dignity]

No Malky, working on something else for the site so will try this tomorrow evening!

Here is hoping yon Bubbly Jock is not interested in IT stuff or he'll be on here saying we should just go onto Messenger or the likes!

Cheers anyway!

Like Malky said earlier, it's virtually impossible to prevent a determined user from saving a copy of an image shown on a website.

Personally I'm against the disabling of right-clicks and stuff on principle.

Cheers
