He pensado en crear UploadFile1, UploadFile2 etc..y asi las guarda donde quiero, pero lo veo un poco chapucero y demasiado codigo repetido, no?
Código PHP:
   if ($_FILES['wallpaper1']['name']!=NULL) {
        $Wallpaper_1=UploadFile("wallpaper1");
    }
    if ($_FILES['wallpaper2']['name']!=NULL) {
        $Wallpaper_2=UploadFile("wallpaper2");
    }
    if ($_FILES['wallpaper3']['name']!=NULL) {
        $Wallpaper_3=UploadFile("wallpaper3");
    }
    if ($_FILES['wallpaper4']['name']!=NULL) {
        $Wallpaper_4=UploadFile("wallpaper4");
    }
    if ($_FILES['wallpaper5']['name']!=NULL) {
        $Wallpaper_5=UploadFile("wallpaper5"); 
    Código PHP:
   function UploadFile($uname)
{
        global $_FILES;
        global $path;
        $type = substr($_FILES[$uname]['type'],0,6);
        if(!isset($_FILES)){
            $error = "You must select a valid file.";
        } else if($_FILES[$uname]['error']!=0){
            $error = "An unexpected error occurred.";
        } else if($type != 'image/')
        {
            $error = "The file you have selected is not a valid image file.";
        }
        if (! $error)
        {
            $_IMAGE = array();
            $_IMAGE['name'] = $_FILES[$uname]['name'];
            $_IMAGE['size'] = $_FILES[$uname]['size'];
            $_IMAGE['date'] = date("D d F Y");
            $_IMAGE['type'] = substr($_FILES[$uname]['type'],6);
            $_IMAGE['code'] = microtime();
            $_IMAGE['name'] = htmlentities($_IMAGE['name']);
            $_IMAGE['size'] = htmlentities($_IMAGE['size']);
            $_IMAGE['date'] = htmlentities($_IMAGE['date']);
            $_IMAGE['type'] = htmlentities($_IMAGE['type']);
            $_IMAGE['code'] = htmlentities($_IMAGE['code']);
            $type = htmlentities($type);
            $type = strtolower($_IMAGE['type']);
            if (strtolower($type) == "pjpeg") { $type = "jpeg"; }
            if (strtolower($type) == "x-png") { $type = "png"; }
            if(checktype($type) == false)
            {
                $error = "That file type is not allowed.";
            } else if($_IMAGE['size']>5024000){
                $error = "That image is too large.";
            }
            if (! $error)
            {
                $target_path = $path."imagenes/wallpapers/";
                $_IMAGE['name'] = $_FILES[$uname]['name'];
                $rnd = rand(0,1000000);
                $name = substr($_IMAGE['name'],0,strpos($_IMAGE['name'], ".")).'-'.$rnd;
                $name .= ".".$type;
                $target_path = $target_path . basename($name);
 
                if(move_uploaded_file($_FILES[$uname]['tmp_name'], $target_path))
                {
                    return $name;
                } else
                {
                    echo $_FILES[$uname]['tmp_name']."<br />".$target_path."<br />t";
                    return false;
                }
            }
        } else
        {
            echo $error;
            return false;
    }
} 
    Código PHP:
   $target_path = $path."imagenes/wallpapers/";
