You know on some websites, especially art websites, how it doesn't enable you to the save the picture? How do you do this?

Is it some sort of HTML code? [img]graemlins/saywhat.gif[/img]

Dunno.

But I can tell you that it takes a competent internet user approximately 20 seconds to pull the picture from the cache (and thats assuming you use deceptive filenames) so why bother?

Well, they've probably disabled the right-mouse-click with a reason; but either way, you could always check your Temporary Internet Folder for those images; they should be in there somewhere.

<span style="color: lightblue">If it's a disabled right click, that's JavaScript... same thing can prevent you from looking at the source code, until you discover the "View" menu.
It's also not a good way to protect images - Water Marks can't be bypassed.

<font color=33CC33>You can't do that, but if you have Win XP you can move your mouse pointer over a picture and wait for menu bar to show. Then click on save picture as icon.</font>

That´s not a winxp feature, it´s a IE 6 feature. ;) Works for win2k as well as for win98 if you have IE6.

As Lennon and Andrewas said, this is not a very good way to protect you images. If you still want to try it here the script my hubby made for me.

NO problem. Beware that most people find this very annoying. ;) I also have a script that allows no clicking whatsoever on you site. :D Used that on my university forum once as an April fools joke. :D

Hehe well until Willow came along I was about to tell you that it's JavaScript etc. :D
IIRC in ASP you can also prevent files being cached - now THAT is how you stop people stealing your images :D Of course you need to be on a host that runs Internet Information Services Server.

More specifically you have to set the "Cache-Control" HTTP header to "no-cache". Then people's browsers will simply not cache your images. Use this in conjunction with right-click disabling or whatever and people will really be annoyed :D

As I said this requires that your site is made with a server-side scriping technology like ASP, JSP or PHP.

But be aware that this depends on the browser following the HTTP standards regarding the no-cache rules. It wouldnt be a massive programming task to make a 'browser' that simply pulls a given page and saves all images to disc.

And if its smaller than the screen, theres nothing to stop someone using the print screen function to capture it. (Although that saves a .bmp, re-encoding it to a .jpg would lose significant quality).

In the end, if you put something on the net and someone wants to steal it, its stolen.

One tactic that might work is putting a smaller/marked version on public display, and making the full thing members-only. At least that way the onyl thing thats easily stolen is a limited version. Of course, charging for membership might not be acceptable and if membership is free theres little benefit.

Ooo first you "dunno" and now you're an expert all of a sudden [img]tongue.gif[/img] :D

Yeah it's a simple programming task to make a simple browser that saves all content regardless of the cache control header. However, the general masses will not be able to program such a browser. Anyway, you're right, the marked version for public display is probably the best idea. Or just have a thumbnail up for display. Also, you can script password access with any server-side scripting technology.
If someone wants to get something off the web - they will.
JavsScript is never a solution in itself because browsers such as Mozilla have the option to turn all scripts off and then where's your fancy right-click blocking script? :D

I am not sure if this works, but couldn't you just select the picture and Ctrl+C it?

No that doesn't work. Try selecting and Ctrl+C -ing the flag in your sig.

There's a program called 'Screan Shot' by Borderbund that will save any screen to a file or folder. I've used it in games to save a location in an active game. It's fairly cheap as software goes. You can save the whole screen or any section of the current screen.

You don;t need that - you can always capture the contents of the current screen by pressing alt + print screen.

Actually, it did work with Vedrans sig ;)

Didn't work for me. I'm using Mozilla. Maybe that's why.

Avoiding script problems is fairly simple. Disable running scripts in your security settings. Viola, all scripts are blocked! Of course, that may also mean that other script related things on the page won't work either. It's give and take you know. ;)

BTW: The WSH (Windows Scripting Host) controls the compiling of text based scripts in web pages.

I just found out you can drag and drop pictures from a browser onto your desktop and it becomes a file. dunno if this is winXP only but it looks like a simple security hole to me :(

I think that feature is available on all OSs. [img]smile.gif[/img] Not sure if it is a loophole in security though. ;)

all i meant is that the security suggestions posted here have not accounted for this very simple way to steal piccies (xcept membership idea). is there a way to stop this to save GokuZool any more hassel?

Javascript actually...

I can't post the code here but I can refer you to www.funky-chicken.com

So thats who Borderbund are, my spyware killer keeps killing this programme every other time I am on IW.. any more info on it/them?
