Image Locations

Nextgen gallerys default to
wp-content/blogs.dir/%BLOG_ID%/files/

if you FTP there and upload files, make sure to go to Manage Gallery and “scan folder for new images”

 

The media library uses
/wp-content/uploads/

and then folders by date.

When inserting a single image into a page, from the media library/upload will auto link to that image, from nextgen gal will be unlinked.
