Does anyone have code that would prevent the XP Save image feature when viewing a web page? Is it html code or javascript?

Thanks

Is the web page embedded in AMS or published on the web?

Wouldn't matter, images are all in your users temp folder either way. One thing I have found is that you cannot serve *and* protect images. It's one or the other. Takes 2 seconds to make a 32-bit screencap. :)

There are tons of "no right click" javascripts on Google though. Although I advise against them, right clicking is a vital part of surfing, plus they can be very, very, very easily circumvented and they don't prevent image caching anyhow. There's a pragma no-cache tag you can check out on Google too but again, none of those things will truly protect anything...

I realize its next to impossible to stop every way to copy things.
However, there are some preventative measures that can be taken to *help* stop the average joe. A possible for the Screen cap, you could use:

<body onload=setInterval("window.clipboardData.clearData()",20)>

If this was used in a page embedded in AMS it would be easier to control than a published page.
Additionally, to stop right-click save, you could put images in a table as the background and have a transparent null image on top so they can only save that one using right click.
No doubt theres others too ..

Just some thoughts

In both cases the images are sitting neatly in your temp internet files folder politely awaiting god only knows what type of abuse.

In the end, it's all about making it a bit more difficult for the average person to circumvent. You can't stop someone who is determined to steal something, but you can take away the easy route - basically making sure that the average law respecting user knows it's wrong to steal...

My qualified opinion is that the, "I'll re-use this image but ONLY if I can right click it" user doesn't exist. Urban myth. :) There are just people who do and people who don't. That being said the people who do will indeed screencap and/or pop open a temporary internet files folder from my experience, so these are the two key points you need to address...
