sounds like you bought waterslide decals. No experience with them.
You can however get simple peel off decals, essentially stickers.
In either case, you should put some clearcoat (I use spray clear acrylic from an autoshop) otherwise you risk smudging the image. The decals, and inkjet inks themselves, are not water tight by themselves.
Lots of examples of ones I have done on my blog
