Hi,
I know by default image/picture integration is not there in this module, but it can be achieved y using ldapdirectory module.

download this module http://drupal.org/project/ldapdirectory and enable it and also "view ldap directory block" permission

then edit ldapab.display.inc

after this code

  if ($entry->exists('cn')) {
    drupal_set_title($entry->getValue('cn', 'single'));
  }

add the following code

$photouid=$entry->getValue('uid', 'single');
if ($entry->exists('jpegPhoto')) 
{
  
  $rows[]=array(
   array('data' =>'Photo', 'header' => TRUE),
 '<img src="'. url("ldapdirectory/picture/1/$photouid") .'" height="150px"></center>',
);

where "uid" is the ldap attribute containing one user details.

although ldapdirectory itself can be used instead of ldapcm, this is just for information, for those who like ldapcm.
