I need help. I need to merge pictures of real buildings with either real or fake pictures of a roller coaster. (Real or fake coaster, that is.) I am trying to create an image of what a real location would look like if there were a roller coaster built there. What are my best options for trying to do this quickly and easily? Furthermore, if there is anyone who just knows how to do this, would you be willing to make it happen if I supply the pictures?
Thanks in advance.
