Bootstrap缩略图图像间距

Question

我有一个奇怪的问题。出于某种原因，我的缩略图中的图像不会“填充”缩略图图像部分。缩略图边框与图像之间有一些间距。

我正在尝试移除您在iamges周围看到的空白区域。我已经尝试了width: 100%

 .thumbnail img {
    width: 100%;
}

    .thumbnail {
    box-shadow: 0 0 23px black;
}

我希望img一直走到缩略图的边缘

HTML代码

<div class="col-md-9">
                        <div class="row hidden-xs hidden-sm">
                            <img src="../images/Signs/SignsFrontPageBanner.gif" class="img-rounded  header" style="max-width: 100%; ">
                        </div>

我通过将padding: 0px !important;添加到.thumbnail修复了问题，它需要！important
