Cut just thumb of member are simple:
BxDolBlogs.php
function GenBlogLists
here quite at end of function:

$sRetHtml .= <<<EOF
<div>
<div class="clear_both"></div>
{$sCont}
<div class="cls_res_info_nowidth">

just change to

$sRetHtml .= <<<EOF
<div>
<div class="clear_both"></div>
<div class="cls_res_info_nowidth">

:)
so I cut {$sCont} here
