请问全局表单里的图片字段如何调用？

<div class="product-card" style="float: left; margin: 0 20px 20px 0;">

  <div class="card-inner">

      {form form=scsp order=inputtime num=10}

    <img src="图片地址" alt="{$t.title}" class="product-image">

    <div class="card-content">

      <h3 class="product-title">{$t.title}</h3>

      <div class="price-section">

        <span class="original-price">¥{$t.yuanjia}</span>

        <span class="discount-price">¥{$t.disconnect}</span>

      </div>

      <div class="buy-section">

        <a href="{$t.link}" class="buy-btn">直达购买</a>

        {/form}

        <span class="platform-tag">京东</span>

      </div>

    </div>

  </div>

</div>
