Are image maps supported in chrome and firefox? w3schools seems to suggest they are.
Given this, why would the following HTML fail? (Image is displayed but no links work - It does work correctly in IE)
<img src="Images/backgroundFinal.png" usemap="#mainImageMap" alt="MainBackground" style="border: none;" />
<map id="mainImageMap">
<area shape="rect" alt="Home Page" title="Home Page" coords="309,198,413,223" href="Default.aspx" target="" />
<area shape="rect" alt="About me" title="About me" coords="245,334,319,353" href="About.aspx" target="" />
<area shape="rect" alt="Gallery" title="Gallery" coords="437,271,497,300" href="Gallery.aspx" target="" />
<area shape="rect" alt="Tattoo" title="Tattoo" coords="249,478,307,503" href="Tattoo.aspx" target="" />
<area shape="rect" alt="Contacts" title="Contacts" coords="395,521,464,544" href="Contact.aspx" target="" />
</map>
Try changing <map id="mainImageMap"> to <map name="mainImageMap">. You can keep the id if required but just make sure a nameattribute` is there.
