This project is looking for a new maintainer. Please post in the issue queue if you are interested.
Please see LinkIt and LinkIt Picker for actively developed replacement for Node Picker.
Please use the following module to MIGRATE YOUR LINKS from Node Picker format: Node Picker Migrate.
This is a rewrite of the module TinyMCE Node Picker that aims to support additional editors besides TinyMCE. In the current ALPHA release TinyMCE, FCKEditor and CKEditor are supported. Support for additional editors such as openWYSIWYG and YUI Editor will be added if there is a demand for it.
Node Picker
Node Picker provides a button in supported editors that displays a list of links to content. Choosing a link inserts it into the editor.
The module includes template files which can be edited for your theme, but should not require theming to display correctly.
It also creates two views called nodepicker_nodes and nodepicker_taxonomy which can be edited to change the results that the link picker displays.
