Imagegrab through php on locked computer

Hello,

I have the following code for taking screenshots of a website using php. The problem is that I want these screenshots to be taken through a remote computer (a dedicated server) and the image is not taken if I don't have the computer open with the remote desktop. The user is logged in but if the window of the remote desktop is not opened on my computer the screenshot appears black. I tried even to schedule the script to run from the remote computer but that didn't work as well.

Any ideas?

$Browser = new COM('InternetExplorer.Application');
$Browserhandle = $Browser->HWND;
$Browser->Visible = true;
$Browser->Fullscreen = true;
$Browser->Navigate('http://www.mysite.com');
while ($Browser->Busy) {
com_message_pump(8000);
}
$img = imagegrabwindow($Browserhandle, 0);
$Browser->Quit();
imagejpeg($img, 'screenshot.jpg', 100);

Open in new window

That requires the browser in the dedicated server to be open and to be on focus because it takes a screenshot of what the browser sees.

How about using this instead?

you may also try thumbalizr.
code here: https://github.com/mptre/thumbalizr (site at thumbalizr.com)

http://www.shrinktheweb.com/ too takes screenshot - they have both free and paid API.

http://www.websnapr.com/ is also very easy to use, it provides screenshot of the site

If you have a linux box, try using wkhtmltoimag.
Details here: http://www.codediesel.com/php/taking-screenshots-of-websites-in-php/

hope this helps :)

Forgot to mention that the page I want to take screenshots of, has flash also. I tried the wkhtmltoimag solution and some API's for screenshots and didn't work.

Any other way, even command line could work for me if you have anything in mind.

Thank you very much!
