I just created a header using Adobe photoshop
how do I link it to my web page
I saved as header.psd
(i think this is how) first save it as a different type of file usually jpg's/gif's or png's work best then make a new html document then
<a href="WEBPAGE.html" ><img src="header.FILETYPE" border="0"></a>
psd are not web compatible, switch to either a jpeg, gif or png format.
