Image "disappears" under menu

Question

I'm working on a Tictail shop and i have one problem that i just can't get my head around. As you can see here http://i.stack.imgur.com/rXOJf.png, the picture (which is supposed to be on the front page) falls under the menu. I don't know what to do. My first thought was to check the "header", but i couldn't solve it.

/* HEADER
**********************************/
#mast {
  position: fixed;<br>
  border-top: 1px solid #fff;<br>
  background: #fff;<br>
  left: 0;<br>
  height: 100%;<br>
  width: 280px;<br>
  z-index: 300;<br>
  text-align: center;<br>
  padding: 50px 0 0 0;<br>
  overflow: auto;<br>
  overflow-x: hidden; }

Is it something else i should look for? I also checked the "main-container", but no luck.

#main_container {<br>
  margin: 0 auto;<br>
  padding: 80px 0 0 0; }

Would be deeply greatful if someone could help me out!

我已经使用div-tag在我的屏幕上工作了，但是当我测试较小屏幕的分辨率时，图片仍会在导航下消失。

我不明白。难道我不能像导航墙一样进行导航。主容器中的内容无法突破＆＃39;？
