Greetings,

When I run example.php, this works great.

//display html image tag for captured webpage
$screenShot->displayImage();

If I run example.php with

$screenShot->capturePage();
$screenShot->downloadCapture('test.png');

The following error appears:
Fatal error: Call to undefined function getimagesizefromstring() in /home/rydscom/public_html/php/screenshot.class.php on line 105

Any guidance to fix the error would be gratefully received.

And thank you for the script.

Bill

You need PHP version 5.4 or greater.

There is a work-around for older versions as long as your settings allow_url_fopen...

In the screenshot.class.php you will need to replace the line...

$this->imageInfo = getimagesizefromstring($this->capture);

with...

if(!function_exists('getimagesizefromstring')){
$uri = 'data://application/octet-stream;base64,'.base64_encode($this->capture);
$this->imageInfo = getimagesize($uri);
}else{
$this->imageInfo = getimagesizefromstring($this->capture);
}

I haven't tested this, however it should work in theory.

Dave
