Border to an image/area

[Zanezeroqwe]

I have this css:

.border {
border-top: 0px solid #7F7F7F;
border-left: 1px solid #7F7F7F;
border-right: 1px solid #7F7F7F;
border-bottom: 1px solid #7F7F7F;
}

But I want to have pictures for my border (something like this for the left border: )

How might I do this?

If you want rounded borders then:

.border {
  border: 1px solid #7f7f7f;
  border-radius: 10px;
}

Else you can go look at the border properties:
