    Default url screenshot php

    I try to take url screenshots in php, and I try a script from php site with the fuction imagecreatefromjpeg, like this one:
    PHP Code:
    Header( "Content-Type: image/jpeg");
    function LoadJPEG ($imgURL) {
        ##-- Get Image file from Port 80 --##
        $fp = fopen($imgURL, "r");
        $imageFile = fread ($fp, 3000000);
        ##-- Create a temporary file on disk --##
        $tmpfname = tempnam ("/temp", "IMG");
        ##-- Put image data into the temp file --##
        $fp = fopen($tmpfname, "w");
        fwrite($fp, $imageFile);

        ##-- Load Image from Disk with GD library --##
        $im = imagecreatefromjpeg ($tmpfname);

        ##-- Delete Temporary File --##

        ##-- Check for errors --##
        if (!$im) {
            print "Could not create JPEG image $imgURL";
        return $im;
    $imageData = LoadJPEG("");
    imagejpeg($imageData, '', 100);
    But when I execute the script not appear any image contain the url screenshot.
    If I execute the script in the script page (imagem_url.php) appear this phrase:"".

    If I call the image in other page don't appear anything, just a blank page.

    I think I have to change something in the php.ini for authorize the image url capture, but I don't know what I have to change.

    If the reason not is php.ini, what kind of problem my script have?

    The best regards,

    When I saw your post title, I was more than happy because someone can do it in PHP. However, your method is not correct, when you use fopen to open a URL, you will only get the HTML! How can you expect to get the actually rendered graphic of that webpage?

    Uhhh... yes... what you are trying to do is waaaaaaaaaaaay more complex than that! What you are attempting is a screen grab of a page as it might be rendered in a web browser

    Off the top of my head I'd be looking at piping a wget into some sort of screen capture ( standalone... not web based ) application, or running a dedicated box that can fire up an instance of a web browser and "snapshot" the url.

    Alternative is to use one of those free site testing services that do a snapshot, and download the image from there... but usually there is a delay unless you give them $$.
