General Support: Help with "limit the amount of images within a row"

Hi peeps,

Can anyone help me? I have Plogger v3.0 working with lightbox, Im trying to limit the amount of images/pictures (4 or 5) on each rows but having some problems. Here are the codes for the page: thanks.

<?php
plogger_get_header();
print '<div id="thumbnail_container">';
if (plogger_has_pictures()) {
print '<div id="overlay2">&nbsp;</div>';
print '<ul class="slides">';

while(plogger_has_pictures()) {

plogger_load_picture();

// display thumbnails within album
// generate XHTML with thumbnail and link to picture view.

$capt = plogger_get_picture_caption();
$img_id = "thumb-".plogger_get_picture_id();
$imgtag = '<img id="' . $img_id
. '" onmouseout="document.getElementById(\'overlay2\').style.visibility = \'hidden\';"
onmouseover="display_overlay2(\''.$img_id.'\', \''.plogger_picture_comment_count().'\')" class="photos"
src="'.plogger_get_picture_thumb().'" title="'.$capt.'" alt="'.$capt.'" />';
if (lightbox_on()) {
print '<li class="thumbnail">yyyh<div class="tag"><a href="'.plogger_get_source_picture_url().'" title="'.$capt.'" rel="lightbox[test]" >' . $imgtag . "</a><br />";
}
else{
print '<li class="thumbnail"><div class="tag"><a href="' . plogger_get_picture_url() . '" >' . $imgtag . "</a><br />";
}
print plogger_download_checkbox(plogger_get_picture_id());

print '</div></li>';
}


print '</ul>';
}
else{
print '<div id="no-pictures-msg">There are no pictures in this album.</div>';
}

print '</div>';
plogger_get_footer();

?>
