How to upload multiple images as multiple nodes?
Check out Bulk File Nodes Module


  Bulk File Nodes allows a user to upload or import many files at once,
  and have many individual nodes created, one for each file . Where this
  module significantly differentiates from other modules like Bulk Media
  Upload is that after uploading/importing the file(s), the user is
  given the opportunity to edit all of the fields for each node in a
  single form.
  
  Another form to the right acts as a bulk settings form where each
  field that has a value is applied to each node's corresponding field,
  except where the user has overridden the bulk settings form by
  specifying a value in the field of an individual node.
