HTML Code:
<table style="width:{$picturebit_width}px; margin:5px; float:$stylevar[left]" border="0" cellspacing="0" cellpadding="0">
Replace with:
HTML Code:
<table style="width:{$picturebit_width}px; margin:5px; <if condition="$_GET['do'] != 'grouppictures'">float:center<else />float:$stylevar[left]</if>" border="0" cellspacing="0" cellpadding="0">
