Hi. I'm not experienced with this stuff, but I can give you some pointers
which will hopefully be helpful.

1. how can I disable icons presenting content (like icon of an image

I guess you want to set the dconf key "org.gnome.nautilus.preferences
show-image-thumbnails" to "never" and lock it down. The information on this
page may be useful: https://wiki.gnome.org/dconf/SystemAdministrators

2. I have made files in some folder unreadable. When I copy an image

Not sure if relevant, but the keys under the schema
"org.gnome.desktop.thumbnailers" control external thumbnailers per MIME
type.
