As it is one big image you can use a image map to create links. So for the image you got there it would look something like that:
<map name="store">
<area shape="rect" coords="79,251,136,366" href="blinds.htm">
<area shape="rect" coords="143,253,165,400" href="map.htm">
<area shape="rect" coords="171,252,234,366" href="shutters.htm">
<area shape="rect" coords="255,252,305,365" href="awnings.htm">
<area shape="rect" coords="311,253,362,366" href="awnings2.htm">
<area shape="rect" coords="370,252,393,399" href="aboutus.htm">
<area shape="rect" coords="416,253,489,365" href="aluprod.htm">
<area shape="rect" coords="496,253,517,396" href="contactus.htm">
<area shape="rect" coords="549,254,615,366" href="canvasspec.htm">
</map>
<img src="Storefront1.jpg" border="0" width="700" height="500" alt="" usemap="#store">
