Thanks for your reply Matt. The GROUP idea works and, if I name the GROUP the same as the layer I'm attempting to mask, seems to prevent the unmasked layers from displaying. However, since it appears that a layer can only be in one GROUP, this means that I have to duplicate my inline mask layer for each image layer I'm attempting to mask.
