no worries.. sorted it. I changed the replacement 'popup with title to;
Code:
<a href="#" onclick="return false;" class='DEF' onmouseover='GAL_popup(this,"$gal_offset", $gal_width, "$gal_box_style", "$gal_description", "$gal_description_style", "$gal_title", "$gal_title_style");' onmouseout='GAL_hidepopup();'>$gal_text</a>
This is a great addon, look forward to seeing more of your work.
