In some neighborhoods, every other tree on block after block has been pastered with a sign.What is the function on , can it be omitted?Thanks!

I wouldn't omit it; it links the trees to the location.

Can we say:1. we pasted the window with a picture.
2.The window was pasted with a picture by us.
3.The tree was pasted with a picture.If so, the "on" in the original one should or can be omitted. I am afreaid. What about you? Thanks!
