Is publishing a picture bearing the name "The Female Deity" considered an act of disbelief (kufr), even though the owner of the picture stated that she does not believe in the disbelief contained therein?

The questioner did well in forbidding the girl from this evil and enjoining her to delete the picture, and in not judging her to be an unbeliever; because a specific individual is not judged to be an unbeliever except by the fulfillment of the conditions for declaring someone an unbeliever and the absence of its impediments. Not everyone who falls into disbelief has disbelief fallen upon them.
