What would be the problem, registering the file extension on client?

[hadad]

the problem is how to structure a file that only my application can read.This file holds an image and a structure of an html document.

Sounds like an serialized xml document, optionally in binary format. File itself is readable by any application or user but to understand its content is application specific.
