Image saving to local driver but not saving to database

I have this in my controller to store background image

$currentBackgroundPicture = $user->backgroundPicture;
        if($request->backgroundPicture != $currentBackgroundPicture){
            $toske = time().'.' . explode('/', explode(':', substr($request->backgroundPicture, 0, strpos($request->backgroundPicture, ';')))[1])[1];
            Image::make($request->backgroundPicture)->save(public_path('img/profile/').$toske);
            $request->merge(['backgroundPicture' => $toske]);

            $backPhoto = public_path('img/profile/').$currentBackgroundPicture;
            if(file_exists($backPhoto)){
                @unlink($backPhoto);
            }
        }
$user->update($request->all());

If i should put the local store image name inside the database manually and i try to upload another image i get this error

    "message": "Unable to init from given binary data.",
    "exception": "Intervention\Image\Exception\NotReadableException",
    "file": "C:\MAMP\htdocs\Main Api\api\vendor\intervention\image\src\Intervention\Image\Gd\Decoder.php"

it is saving inside public path but it is not storing inside the database table
