thumbnail backround setting

        }

        // Free a memory from the source image
        imagedestroy($sourceImage);

        // Save the resulting thumbnail
        return $targetImage;
    }

creates thumbnail with black backround like this

but white is needed.

what to add and where ?

A clue...

/* create an image */
$im = imagecreatetruecolor(400, 30);

/* define some colors */
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);

/* fill the image with a color */
imagefilledrectangle($im, 0, 0, 399, 29, $white);

doesn't work for me because

$result = imagecopy($targetImage, $sourceImage, 0, 0, $X, $Y, $W, $H);

runs it over with black again.

I have done something similar in the past, here is my code, you should be able to amend it to suit....

$size = GetImageSize ("$path_to_image");   // set image name here
    $old_width = $size[0];
    $old_height = $size[1];

    if($old_width/$old_height < 1.33334){//is it landscape or portrate?
        $new_height=300;
        $new_width=round($old_width/$old_height*300);
    }else{
    $new_width = $width;
    $new_height = round($old_height * $width / $old_width);  
    }

    $source_path=$where_temp;   //Source File path
    $destimg=imagecreatetruecolor($new_width,$new_height) or die("<p>Problem In Creating image</p>");

    $srcimg=ImageCreateFromJPEG($source_path.$image_name) or die("<p>Problem In opening Source Image</p>");
    // imagecopyresampled for better quality
    imagecopyresampled($destimg,$srcimg,0,0,0,0,$new_width,$new_height,ImageSX($srcimg),ImageSY($srcimg)) or die("<p>Problem In resizing</p>");
    //create an image 400x300
    $base=imagecreatetruecolor(400,300);
    
    $white= imagecolorallocate($base,208,244,255);
    //make white background
    imagefill($base,0,0, $white);
    //calculate the starting x position to place image in center of background
    $xpos=round((400-$new_width)/2);
    //merge the two images
    imagecopy($base,$destimg,$xpos,0,0,0,$new_width,$new_height);
    
    ImageJPEG($base,$destination_path.$image_name) or die("<p>Problem In saving</p>");
}
