Maybe heredoc is an even easier option ...
if (trim($pic) <> "") {
echo <<< END_DIV
<div class="proddetailpics">
<a href="#" class="color_thumb">
<img src="/imagedir/$pic" alt="$itemgroup $itemsubgroup"
width="60" height="60" onclick="MM_swapImage('prodimage',
'','/imagedir/$pic', 0);" border="0" />
</a>
</div>
END_DIV;
}
No escaping of quotes, as long as you use " for html attributes and '
for javascript strings.
