In your file templates/tmpl_xxx/scripts/index.php look for an SQL query like that:

$featured_res = db_res( "SELECT `Profiles`.`ID`, `Pic_0_addon`, `ProfileType`, `NickName`, `Headline`, `Sex`, `Country`, `DateOfBirth`, `DateOfBirth2` FROM `Profiles` WHERE `Status` = 'Active' AND `Featured` = '1' ORDER BY RAND() LIMIT $feature_num" );

and change it to:

$featured_res = db_res( "SELECT `Profiles`.`ID`, `Pic_0_addon`, `ProfileType`, `NickName`, `Headline`, `Sex`, `Country`, `DateOfBirth`, see more `DateOfBirth2` FROM `Profiles` WHERE `Status` = 'Active' AND `Featured` = '1' <b>AND `Picture` = '1'</b> ORDER BY RAND() LIMIT $feature_num" );

You can add this code - AND `Picture` = '1' - to other SQL queries, depends of your needs...
