There are several ways, but the best one depends on the type of the image.

If you want all the white to be replaced with transparent, you can use the curves+ plugin: select advanced, set input to luminosity and output to alpha. Then invert the curve.

If your image is black and white you can use the black and alpha plugin.

There are also other plugins that can accomplish this.

You can also simply use the magic wand to select the area you want transparent, then click delete to turn it transparent.

In this case I think the magic wand may be the best method, since there is also white inside the image. After you delete the white around the image, use object feather to get rid of pixelation around the image.

In addition, you also need to save in a format that supports transparency. PNG is probably the best format to use for this image. If you save it as JPG (which is the current format) you'll still have a white background.
