function convertLQ($image_path)
{
ClearStatCache();
$file = basename($image_path);
$dirname = dirname ($image_path);
// set save path + name
$save_path = $dirname.'/LQ/'.$file;
// Load image
$img = null;
$ext = strtolower(end(explode('.', $image_path)));
$image_path = htmlentities($image_path);
if ($ext == 'jpg' || $ext == 'jpeg')
{
$img = @imagecreatefromjpeg($image_path);
}
else if ($ext == 'png')
{
$img = @imagecreatefrompng($image_path);
}

// If an image was successfully loaded, test the image for size
if ($img)
{
// Get image size and scale ratio
$width = imagesx($img);
$height = imagesy($img);
$scale = maxHeightLQ/$height;
// If the image is larger than the max shrink it
if ($scale < 1)
{
$new_width = floor($scale*$width);
$new_height = floor($scale*$height);
// Create a new temporary image
$tmp_img = imagecreatetruecolor($new_width, $new_height);
// Copy and resize old image into new image
imagecopyresized($tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
