Missing Upload Images Link

I'm not seeing the Upload Images item in the menu bar. I have an Images namespace set up. Site is running VBulletin 4.2.0 I can go into the Vbulletin navigation manager and add the menu item under the Wiki tab, but I don't know what to enter for the Target URL or Show Permissions Name

Show Permissions Name: vw_links.show_upload
Target URL: {vw_links.upload_link}

Thanks. That works for me.
