VHTV naming/logo is not required for images when those are zoomed in to some specific subject/object. That’s just too much hassle for most of viewers to add it manually in this case.
VHTV naming/logo is required for videos, though it might be acceptable to put those for zoomed in parts of short videos. Part-length and full length scenes must include VHTV naming/logo.
In addition, deliberate cropping of naming/logo is prohibited when posting image or video which obviously would look kind of same without cropping.
Hope it’s clear. Rules are good as long as common sense is present too.
