Adding an Image Via HTML?

I’m very new at this, so forgive me, but I’m having trouble adding an image to this page via html coding:

http://www.trialofthecentury.net/store-2/

The path I’m using to add the image is this:

<img src=”/home5/trialoft/testimage.jpeg” height=”42″ width=”42″>

What am I doing wrong?

Thank you!
