custom image extension

[therealjohndoe77]

Can I give custom extensions to my image file?

I want to secure my image file such that it can only be opened by my application. Is that even possible?

Yes, of course that isn't really very secure. You can set a file extension to anything you want. For example Microsoft docx files are really zip archives, LabVIEW lvproj files are XML, and the list goes on.

How can I do that with an image file?

You just give it a different extension then whatever it might normally be.  Isn't that what you were originally asking to do?
