It has some wonderful images of magnetic resonance microscopy of embryos. This site has wonderful diagrams and a list of useful links to other embryo resources. Lecture tends to go the same way. Medical schools generally view embryology as a way to introduce birth defects and how one goes about treating them. Cell and Molecular Biology courses deal with the gene regulation aspects of the topic.
Most textbooks opt for molecular with some comparative anatomical material thrown in.
Also Cogito Films has some wonderful videos that talk about various model organisms that have significant embryo importance. I trust this helps. You have an exciting job in front of you. The emphasis is a bit too much on humans for my preferences, but does make species comparisons a good deal. Note that the publisher does NOT provide transparancies, which is a problem with the other embryology texts I looked at as well.
