Are there any pictures of this icon bearing myrrh on the internet?
I don't know about this icon on the "Net," nor even if the wonderworking, myrrh-streaming icon I personally was blessed to venerate is depicted on the "Net," but I can assure you from personal experience, that such icons do exist!
I was so caught up in the opportunity to venerate a myrrh-streaming icon of St. Nicholas the Wonderworker when it was brought to a local church for an Akathist to St. Nicholas Service one evening that I also traveled out of state to venerate it at another church the following evening! The aura of holiness surrounding the icon was unmistakable. The myrrh, with a fragrance like roses, if one went up close to the wonderworking icon, could be seen streaming slowly but steadily from the forehead of the Saint, down his face and vestments, to the bottom of the icon, where it was caught by balls of cotton. After being anointed with this fragrant myrrh by one of the priests present, one was given a ball of the cotton soaked with the myrrh together with a paper copy of the wonderworking icon in an envelope to take home and place in one's icon corner. The fragrance from the myrrh remained for several months, and I distributed other paper icons and myrrh-soaked balls of cotton to some sick people unable to come to the church--their myrrh-soaked cotton balls also retained the fragrance of roses for a very long time, and they could anoint themselves for several months.
