Icon/Thumnail in 'Details' Mode

Hi,

Got a new PC and dang..forgot to export my settings :///
Was a lot work to set it up for my personal workflow,
almost there where I was, I had on my viewer always mode 'Details' on and always had icons
for images showing up (the look of the image itself) no idea how I did accomplish that a few years back, went thru most settings but can't find it anymore

It's here in the default toolbars:

Or you can add the Thumbnails column when in details mode, similar to adding other columns.

neh, i tried those options, I think I may be back then used a plugin or something, Sagethumbs, it was
really on 'Detail' mode and saw an icon the exual picture
