Thx nando99 for the try, bu that didn't worked (and also aligned my thumbnails vertically). Here is my postbit_attachmentthumbnail:

<td class="tborder" valign="top" width="$imwidth"><a href="attachment.php?$session[sessionurl]attachmentid=$attachment[attachmentid]&amp;d=$attachment[dateline]" rel="Lightbox" id="attachment$attachment[attachmentid]"<if condition="$show['newwindow']">  target="_blank"</if>><img class="thumbnail" src="attachment.php?$session[sessionurl]attachmentid=$attachment[attachmentid]&amp;stc=1&amp;thumb=1&amp;d=$attachment[thumbnail_dateline]" border="0" alt="<phrase 1="$attachment[filename]" 2="$attachment[counter]" 3="$attachment[filesize]" 4="$attachment[attachmentid]" 5="$attachment[description]">$vbphrase[image_larger_version_x_y_z]</phrase>" /></a><if condition="!empty($attachment[description])"><div class="alt2" style=" padding:2px;"><span class="covercaption">$attachment[description]</span></div>
</if>
</td><if condition="$show['br']"></tr><tr></if>

Maybe there is something wrong inside it
