In Business Intelligence solutions sometimes you may need to publish InfoPath forms to a Form Library or to create a slideshow based on a picture library. But by default you can’t create a Form library/Picture Library when your site is created based on Business Intelligence Center.
If you click Site actions-> More options->Library, you see only following Library templates.
How can I enable Form Library?
Go to Site actions->Site settings
Under Site Actions heading select Manage site features. Then activate Team Collaboration List. Again go to the create window, here you’ll see additional libraries such as form Library, Picture Library and Wiki Page Library are enabled.
