Hi...
You can use custom characters with Motion LIVE 2D. These can be standard G3 characters or Free Bone characters. Morph based heads (created from photos)are also supported.
However, you will need to create your character first and save it into your content library. You can't just load a photo and use it with Motion LIVE 2D. It must be a working character you have created.
Regarding the glasses problem this can be tricky to fully resolve. If you can stop glare on the lens you can get quite reasonable results. It can also work if you lower the glasses onto the end of your nose and look over them while using the tracker. Then tilt your head back if you need to see to be able to click the controls.
