$html = file_get_html( "https://www.google.com/search?q=$search_query& tbm=isch" );

should be

$html = file_get_html( "https://www.google.com/search?q=$search_query&tbm=isch" );

A space between search_query& and tbm needs to be removed.

EDIT

<?php

if (isset($_POST['submit'])) {

    include "simple_html_dom.php";
    $search_query = $_POST['image'];
    $html = file_get_html("https://www.google.com/search?q=$search_query&tbm=isch");
    $images = $html->find('img');
    $image_count = 10; //Enter the amount of images to be shown
    $i = 0;
    foreach ($images as $image) {
        if ($i == $image_count)
            break;
        $i++;
        // DO with the image whatever you want here (the image element is '$image'):
        echo $image;
    }
}
?>

EDIT - 2 You should give name attribute to submit button such as:

<input type="Submit" name="submit" value="Click to Submit">

OR use : if (isset($_POST['image'])) { instead of if (isset($_POST['submit'])) {

name attribute is missing in submit button as seen in EDIT-2. You are not getting any error because it never goes inside the if condition. – Ashish Choudhary Oct 20 '15 at 12:28
