Navigation/images question.

Hey i am trying to make my navigation images/ links work so that when people click on it, it will take em to the place they clicked. the code i am think i am spose to use to get a certain image onto it is as follows.

<TD>
<A HREF="#"
ONMOUSEOVER="=''; changeImages('', '/'); return true;"
ONMOUSEOUT="=''; changeImages('', '/'); return true;">
<IMG NAME="" SRC="/" WIDTH= HEIGHT=BORDER= ALT=""></A></TD>

so can anyone tell me what i put in all the quotes and hyphins? I have tried a various amount of things and still nothing.
