Heroes of Might and Magic IV

[Cyrus Annihilator]

Smart people of tSR forum, I have another request for you guys.
I've ripped the sprites from Heroes of Might and Magic 1, 2 and 3 using "third-party" softwares, but for the fourth game there are no such tools.

There is a software capable of seeing the sprites inside the data archive, as you guys can see in this little tutorial. Butr ripping with this software is too painful, I would need to take thousand screenshots...
The sprite files are inside a .h4r file and I was able to open and extract using the "Total Comander" software. These spirte files are .gz files and when I open these files (with 7zip or WinRAR) there is a file without extension inside.

Spoiler

Does anyone knows how can I see the images inside this .gz file?
Can I share one of these files here or is against our rules?

Thanks in advance
