Create multiple photo upload Error!

Hi all,

Create a simple application where user can have many albums and album
can have many photos. User should be able to upload multiple photos
while creating new album by clicking on “Add More Photo”. Photos can
also have tags(comma separated). Thumbnails must be created for each
photo after uploading. Album and associated photos and tags should be
created simultaneously, use multi-model approach here.
