Re: images on the internet

The Alchemedia program doesn't allow for a printscreen to work, and doesn't
put the picture in the cache - at least I can't find it there.
It seems that the javascript involved decrypts the graphic so that you can
only see it in the browser - any other program, like a screen dump of some
kind, will only show the encrypted junk graphic.
A couple of people have said they can copy the protected graphic - but I
haven't seen any follow up from them yet. Maybe a digital camera is the only
way to beat this one.
There's a demo here

I'd like the answer to this as well - this one seems to work.

the files from going into your browser cache, where you fan fish it out.
There is also the PrtScn button that will copy what's on the screen to your
clipboard (or Alt-PrtScn button to copy the active window).
