craftgrrl | mod podge photos on glass plates?

hi, i just joined but have been watching this community for a while and have gotton very inspired by you all.

my question is in regards to mod podging inkjet photos (shiny side out) on the back of clear glass plates. the memories says you should coat the photos with a sealant or hair spray so the ink won't run. i can do that, but i was also wondering if i printed the photos out on regular paper or cardstock would they still run? i wouldn't think the type of paper would matter since it's being mod podged anyway.

any other hints anyone has about mod podging photos to clear glass plates would also be helpful to know before i begin my project. thanks!
