What I want to implement is a web application with a video and a button, that every time a person clicks on that button I get/screenshot/anything else their display and save the jpg/or something on the server.
How can I do that? I heard you can’t do that with javascript. I had an idea of a plugin/flash application? How can that be done? The application will be done in PHP.
Php is a server side scripting language, it has nothing to do with a end users desktop and computer… there is no way to do this with Php or straight html for that matter… you would have to utilize Java, Flash, or something else.
Furthermore, it sounds like what you want to do is a little sketchy in itself and maybe you should think why you want to do this.
