. . . . Magix Video Editor. I remember a wizard that make a slideshow that was like visiting rooms with pictures on walls. . . . .
From your first post in the forum there was the suggestion that you had Movie Edit Pro, as you had Photo Designer installed which came with Movie Edit Pro (MEP) .
However, I have the most likely version of MEP (2015) installed and I cannot find a slideshow wizard or movie template with the effect you describe, nor can I remember there being one in earlier versions.
A bit of a long shot - do you still have a video that was exported using this template? If so then a screen shot from it may help identify the template.
