Where are system pictures/photos located?

[eReS]

Hi

I can see some pictures shown on a tile on start screen but I am not able to locate them in albums.
Is it possible to see all system pictures/photos?
There are of course some pictures in "backgrounds" folder but still there are some that I could not locate in the phone.
Where should I look for them?

regards

what photos were they? If they were on the photo tile, that can be set to pull from all photos, favorite photos or single photo.

For example on a tile I could see an image showing part of the surfboard on a water
I am not able to find this picture in any album.
For sure this is not my picture - it must be one of the system pictures.
But it is not visible in backgrounds folder so where I could find it?
