Looking for pynq_z1_v2.5.img file viewer application soft

Hi all,
I am looking for the viewer to pynq_z1_v2.5.img file.
Could you please teach me the application yo view of .img file ?

The file is a Ubuntu based bootable image. You should burn this to an SD card and use it to boot your board.

If you need help burning the image, or want to check how the file was created, and access the source files, see info here:
