How do I retrieve the first image of two images in a node for VIEWS?

I have tried adding "Image: Image" and "Image attach: Attached images" in Fields. It does not work.

What am I missing?

Say my node has 2 images, how do I get the first one in VIEWS?

[img_assist|nid=933|title=Before|desc=|link=none|align=left|width=300|height=189]
[img_assist|nid=936|title=Before|desc=|link=none|align=left|width=300|height=189]
