PS - open documents, perform action

Am new to this so apologies if this is a mundane question but i just cant seem to get this to work.

I want to add a script to a folder so that whenever any graphic file is put into it, the document is opened in photoshop, a specified photoshop action is performed, then the original file is sent to the trashcan. I also need to batch convert files so i guess that photoshop needs to be told to do them one at a time.

I have tried a few resources with no luck, so i decided to ask. once again apologies for wasting your time :wink:
