Does Snow Leopard not make resource forks when one changes an icon for a file or folder? Tiger used to, and if you viewed hidden files, you would see those, but doing that on Snow Leopard does not show any additional files in the directory.

When images are saved, the icons are shown as little thumbnail pictures of the original if one views them with icon view. Are these thumbnails resource forks or not? If I saved pictures with a Snow Leopard image editor, the thumbnails appear in list view as well, but not otherwise. How does that work?

I can still see resource forks (filename/rsrc) files under Snow Leopard.

I believe the thumbnails and folder position (behaviour) are stored in .DS_Store (equivalent to desktop.ini in Windows), and they are just invisible by default.

When saving images, many image programmes create thumbnail (to the file) at the same time. If thumbnail is included, the file (icon) in Finder should show up with the thumbnail. Also, users can control to preview the folder or not and the Finder may try to generate thumbnails.

I could be wrong on this.

I found the extra files for altered folders inside the folders (as in Windows), but it would seem that the resource forks for files are only split off when one saves the file to a non-Mac file system.

Most of the time, I save images with an editor that does not make extra custom icons, and I did not see any resource forks for the image files. One sees briefly the default icon given by the application, then the thumbnail appears, so I guess the operating system is just showing a small version of the image on the fly?

I am lost here, sorry.

(Perhaps, Don can help.)

Assuming the image files do not have thumbnail in it, the Finder will try to generate a thumbnail (icon preview) for it by default setting. This setting can be disabled under "Show View Options".
I believe they are generated on the fly.

So that is what "Show preview icon" is. Thanks. I turned it off. I do not need thumbnail icons.
