In SmartIT / MyIT, if a person record has a user image selected, such as a photo, then this cannot be removed or set back to the default outline image.
I have been advised ... " ..... this is "As designed" feature. " OOTB.
I think it is not "as designed", but more " as left out "
It does not make sense to have the ability to add a picture, without the ability to remove the picture !
