Crop Tool

Hi, I'm having some trouble with my crop tool. I'm using PS CS, and I used to be able to make my crop tool rectangluar by having the option of moving the sides of the square in and out to make rectangular pictures. but now it only allows me to make a square selection. There are no squares on either side to move it in and out.

I want to be able to make my pictures skinny like the one on the outside of this icon by colourmayfade. I believe I somehow changed the settings, but when i right click on the crop tool option, no other options are available. Can anyone help me solve this problem?
