Shawn, which particular mask is it that you used? Give us
a name of the kit or link so we can check it out. There are
only certain ones that will work with MMS as stated above.
The other masks that are in png form need to be used by using
a program that will "clip" the mask and photo together like
Photoshop or Photoshop Elements.
Most of them that can be used in MMS say something like so easy
to use. Just add a photo and send it backward. THOSE
are the ones that can be used in MMS.
