Iconoclasm is an Islamic heresy. A heresy that, at its root, denies the incarnation of God. St. John of Damascus was a great defender of the Christian faith in the face of Muslim persecution. He defends Holy Icons which can be read here. http://www.byzantineimage.com/in-defence-of-icons
Also, this is a beautiful video discussing Holy Icons and their place in the ancient Church.
Reformed aversion to icons has nothing to do with this. It is a conviction about how the 2nd commanment ought to properly be applied to worship and life.
It is also a recognition that while God has a right to create things in his image, such as mankind in general and the incarnation in perfect union of the divine and human natures of Christ, we as creatures do not have that right.
Perhaps the most well known miracle involving the Holy Icon of the Theotokos and the Christ child.
