I don't know much about painter, but as far as I know I think it's just like a pattern brush.
With your brush selected, go to your brush palette and select texture. You can make the textures yourself by opening your image(s) in a new canvas and manipulating it however, and going to Edit > Define Pattern.
I don't think PS has an image hose thingie.
