Denise, you should really post this in the skinning forum or one of the other general ones. But since my lazy arse hasn't finished the forums and I can't move the post, I will answer it here.

It really depends on how you are doing this. I prefer to put flash in a content area and not in the skin itself. If you still wish to proceed this way, the best advice I can offer is to make sure your paths to the flash resemble the images. I have also noticed in the past that flash loading other flash movies or files in DNN tends to like full http: urls.
