Here is some sam­ple code that allows you to cre­ate a thumb­nail auto­mat­i­cally (assum­ing ImageMag­ick is already installed and func­tional) (based on the imag­ick PEAR module).

Code for dynamic thumb­nails using PHP


// Specify your file details
$current_file = 'image.jpg';
$max_width = '150';

// Get the current info on the file
$current_size = getimagesize($current_file);
$current_img_width = $current_size[0];
$current_img_height = $current_size[1];
$image_base = explode('.', $current_file);

// This part gets the new thumbnail name
$image_basename = $image_base[0];
$image_ext = $image_base[1];
$thumb_name = $image_basename.'-th.'.$image_ext;

// Determine if the image actually needs to be resized
// and if it does, get the new height for it
if ($current_img_width > $max_width)
$too_big_diff_ratio = $current_img_width/$max_width;
$new_img_width = $max_width;
$new_img_height = round($current_img_height/$too_big_diff_ratio);
// Convert the file
$make_magick = system("convert -geometry $new_img_width x $new_img_height $current_file $thumb_name", $retval);
// Did it work?
if (!($retval)) {
echo 'Thumbnail created: <img src="/' .$thumb_name .'">';
else {
echo 'Error: Please try again.';
echo 'No need to resize.';
