And what do you mean by "Image" file.

He means some of the file's content. I can't really explain you, you should have to look into PE file format. (Portable Executable)

> And what do you mean by "Image" file

In this context, a file that contains an executable image. Right at the beginning, it has an image header containing information that the loader uses for creating a process image.

So, all binary executables are image files?

It's just a convention to call it image file. It doesn't mean it's a picture, stop looking at us with that face!

I meant like an image of a partition or a file system.
