TOPIC ; changing size of tiles in the ‘photo’s’ program.

When I initially clicked on the photo tile (from the windows start screen), the program showed a selection line with 4 options :

collectie/albums/personen/mappen.

When I clicked on albums it showed medium large square tiles of all the albums I had made with a 'cover' pic and the title I had given. Suddenly last week, the square tiles were 'halved' and showed just a fragment of the photo and the text was incomplete. what must I do to return to my original tile size or to set the settings I want  - without the system changing them unbidden. 

Thx Robbie
