Images outside root folder in un-zipped car mods.... where to locate?

[Ray Tracer]

I'll use the Bentley Speed 8 AMS for example.... I unzip, get a "root" Automobilista folder, with several JPEGs in the unzipped folder. I sort of often end up with no car previews when choosing from the browser inside AMS.
When you do find such extra pics (not livery/template graphics) where do they belong?

thanks in advance...... buncha rocket surgeons in this realm

P.S. I'd much appreciate any compass headings in my pursuit of ground-level tutelage for track creation from scratch...... I'm hoping to begin with centerline design in AutoCAD, import to 3DS to lay centerline down on a terrain using a Boolean type "merge"...... then offset the centerline for pavement width..... eventually I suppose Track Builder and/or 3D Sim Ed will be a mandatory step to import/export files? I'm figuring on geometry as an initial set of tasks, textures later....?
TIA again

It sounds like those are preview images some modders include in the download. In most cases you don't need them at all.
