At the bottom of the activate.php file in the root of the slideshow plugin "ow_plugins/slideshow/activate.php" you will see these lines
$cmpService->addWidgetToPlace($widget, BOL_ComponentAdminService::PLACE_INDEX);
//$cmpService->addWidgetToPlace($widget, BOL_ComponentAdminService::PLACE_DASHBOARD);
//$cmpService->addWidgetToPlace($widget, BOL_ComponentAdminService::PLACE_PROFILE);
The "//" in front of the last two lines disable these locations. If you remove the "//" these should become available. Just remember. Any time you make changes in cpanel you need to set Dev Mode to true "ow_includes/config.php", and go to your site, and refresh the page. Then set Dev Mode back to false. Just an additional note. Anytime the plugin is updated it will be changed back to the original settings.
