How do I remove the background colour of an image?

[bobdobbs]

I've been given an image to prepare for the web.

I've toggled off the visibility of many layers and delete other layers.
I've selected for the layers that I want to be visible.

The problem is that the image has a background colour.
The colour is visible even when all layers are toggled to be hidden.

This is an issue because I need to produce an image with a transparent background.

How do I remove this background colour?
