Hiya,
First thing is there is no reason to use php to make a picture link to a page as html provides that functionality for you.
<a href="http://www.codeconception.com/jeronet/index.php?section=biz"><img src="path_of_your_img_here"></a>
However if you are just practicing syntax I suppose you could echo that out like this...
echo"<a href=\"http://www.codeconception.com/jeronet/index.php?section=biz\"><img src=\"pathofyourimg here\"></a>";
