@Norbert Ciebilski,
you don´t need a keyword to unpack the photo´s. I do it with 7-Zip, a very good Freeware-Program, without problems.
And there is nothing to install. That are .jpg photo´s / .jpg images, you can use or look ….

…. or delete, cause there you have some nice photo´s, but not more. I make better photo´s. And the most photo´s you can´t use with your photo-program, that are ready photo´s, which are not suitable for editing or creating.
What a huge disappointment that was.
