$file = “icon.gif”;
if($fp = fopen($file,”rb”, 0))
{
$picture = fread($fp,filesize($file));
fclose($fp);
// base64 encode the binary data, then break it
// into chunks according to RFC 2045 semantics
$base64 = chunk_split(base64_encode($picture));
$tag = ‘<a href=”http://www.britblog.com/”><img ‘ . “n” .
‘src=”data:image/gif;base64,’ . $base64 .
‘” alt=”British Blog Directory” width=”80″ height=”15″ />’;
