Not really, because one has to remember what the iconoclasts were saying in regards to having images of Christ. Christians which use imagery heavily, such as Catholics, Orthodox, Lutherans, etc. do not say that having images is mandatory, or that they must be venerated. But the iconoclasts were saying that it was forbidden to have them in any sense whatsoever. The denial of this was seen as a direct attack on the incarnation. It is to this that the council itself pointed to in its condemnation of iconoclasm:
“… we declare that we defend free from any innovations all the written and unwritten ecclesiastical traditions that have been entrusted to us. One of these is the production of representational art; this is quite in harmony with the history of the spread of the gospel, as it provides confirmation that the becoming man of the Word of God was real and not just imaginary, and as it brings us a similar benefit. For, things that mutually illustrate one another undoubtedly possess one another’s message. … we decree with full precision and care that, like the figure of the honoured and life-giving cross, the revered and holy images, whether painted or made of mosaic or of other suitable material, are to be exposed in the holy churches of God, on sacred instruments and vestments, on walls and panels, in houses and by public ways; these are the images of our Lord, God and saviour, Jesus Christ.”
While the iconoclasts did believe in the incarnation, their theology betrayed a pseudo-Islamic view of God. If you look at later iconoclastic movements, like the more extreme Reformed churches, you will also notice subtle (and not so subtle) Christological errors.
You’re right that the apostles do not point to images, but I don’t recall saying that they had to? The relationship between images and the Gospel is implicit. You could say the same about the immaculate conception and the assumption, but what I disputed is that the IC and the assumption have implicit relationships to the Gospel.
