Are you hosting the file from a computer and using iPad as a client or are you copying the file back and forth between the iPad and a computer?
Do you know how to copy the file back and forth like that?
Or how can I just output this images into a folder with specified filename which matches with the record number accordingly?
On a computer or on your iPad? Presumably you want this image on the computer. Export Field Contents can export the contents of a container field storing your image to a location and file name you specify. You can do this by hand or via a script that does it automatically.
I'm sorry for not providing enough information.

And you are right. I would like to use iPad as a client, and my computer collects all clients' data.
After data collections, I need to output those images (captured on iPad) into a folder on my computer.
I will try your way.
Thanks for your reply.
