I have the method for that website for you. - It's just small website anyway so
it's not knowledgable enough to hide real place.

Its content address is anything like this
<http://sowirdsgemacht.com/media/img/img.php?seite=1&b=106&f=o&g=106&y=13&h=1&x=23>
<http://sowirdsgemacht.com/media/img/img.php?seite=2&b=106&f=o&g=106&y=14&h=2&x=24>
<http://sowirdsgemacht.com/media/img/img.php?seite=3&b=106&f=o&g=106&y=13&h=3&x=25>

You can use pattern with any normal grade download manager.
It have many variable to increment so you may require use something as excel
to concatenate and drag running number then send all address to batch download
with download manager/HTT.
***
1. In fact, the necessary variable is h (other variable can be same as first
image.) So you can use download manager program for running h=? number only
2. To get these location, just open the page and open
In Firefox, 'Right click' at normal place -> 'View Page Info' -> Media tab.
Then you can run all page number (h) of that catalog

Hope this help ^^
