problem with httpfilecollection causing duplications

hi the following code is a jquery multiple image uploader which adds an id to a database and saves the file.


The problem is that it is duplicating twice each item I upload and it looks like a problem with the httpfilecollection number of items
any ideas greatly appreciated


thanks
