i have add to template.php
function jocmedia_preprocess_ddblock_cycle_pager_content(&$vars) {
if (($vars['output_type'] == 'view_fields') && ($vars['pager_settings']['pager'] == 'custom-pager')){
$content = array();
// Add pager_items for the template
// If you use the devel module uncomment the following lines to see the theme variables
// dsm($vars['pager_settings']['view_name']);
// dsm($vars['content'][0]);
// If you don't use the devel module uncomment the following lines to see the theme variables
// drupal_set_message('

if ($vars['pager_settings']['view_name'] == 'view_td') {
if (!empty($vars['content'])) {
foreach ($vars['content'] as $key1 => $result) {
// add pager_item_image variable
if (isset($result->node_data_field_img_field_img_fid)) {
$fid = $result->node_data_field_img_field_img_fid;
$filepath = db_result(db_query("SELECT filepath FROM {files} WHERE fid = %d", $fid));
// use imagecache (imagecache, preset_name, file_path, alt, title, array of attributes)
if (module_exists('imagecache') &&
is_array(imagecache_presets()) &&
$vars['imgcache_pager_item'] <> ''){
$pager_items[$key1]['image'] =
theme('imagecache',
$vars['pager_settings']['imgcache_pager_item'],
$filepath,
$result->node_title);
}
else {
$pager_items[$key1]['image'] =
' '" alt="' . $result->node_title .
'"/>';
}
}
// add tooltip variable

// add pager_item _text variable
if (isset($result->node_teaser)) {
$pager_items[$key1]['text'] = $result->node_teaser;
}
