Technically, it can be done easily. You would simply use something like:
loadMovie("imagevue/imagevue2.swf", movieClip);
... remember to use globalpath if the parent SWF is not in the main gallery folder. F.ex.:
loadMovie("gallery/imagevue/imagevue2.swf?globalpath=gallery/", movieClip);
Unfortunately, we haven't be able to do any specific testing and there may be current limitations to the layout if you want to place the gallery in a specific location, and limit the area for the gallery. We will have to look into options for this later ...
For now, you can be sure it will load into your parent fla, but it will by default take the entire stage from movieclip coordinates. I have made an example here:
