The thumbnail is placed under the path D: \ Serious \ phpdev \ test \ images \ thumbs. Here we add a gallery. php file to display all the thumbnails. The Code is as follows:

             Welcome to our Photo Gallery                        
Click on any image to see it full sized.
        
             
   ' : '
   
    ';                $odd = !$odd;                extract($row);                echo '
    ';                echo '
    ';                echo '
    ';                echo '
    ';                echo '
   ';            }                        ?>

$dir . '/' . $image_id.'.jpg">';                echo '$thumbdir . '/' . $image_id . '.jpg" alt="" />';                echo '
'.$image_caption.'
'.$image_username.'
'.$image_date.'
 
    

To see the effect of the thumbnail:

Note the following code:

$ Thumb_width = $ width * 0.10; $ thumb_height = $ height * 0.10; // create a thumbnail $ thumb = imagecreatetruecolor ($ thumb_width, $ thumb_height); imagecopyresampled ($ thumb, $ image, 0, 0, 0, 0, $ thumb_width, $ thumb_height, $ width, $ height); // Save the original image imagejpeg ($ image, $ dir. '/'. $ _ POST ['id']. '.jpg ', 100); // Save the thumbnail imagejpeg ($ thumb, $ thumbdir. '/'. $ _ POST ['id']. '.jpg ', 100); imagedestroy ($ thumb );

We set the thumbnail length to 10% of the original length, and the width to 10% of the original width. Make sure that the width is the same. Otherwise, the image will be distorted. Of course, if this parameter is set to an integer greater than 1, the image is enlarged.
