Determine the file type of your image file.
I suspect you are trying to look into the initrd images. These image files
are compressed gzip images.

You can try extracting the image file then examine it's content.

gunzip -c <path_to_image_file> | cpio -id
The above command would extract the content of the image file in the
current directory.

Hope this solves your problem.

thanks!
