I am making a cake for a girl having her party at a haunted tour place and two of the places are a haunted church and a haunted jail.I have pictures of both and I was going to use the wilton candy chocolate to make silhouettes of both buildings along with a cemetery and the old gates so what is the best way to do this????

You can either pipe it (flooding technique) or make a silhouette out of flooded chocolate (put a paper stencil over the chocolate and cut it out) or do that same technique with candy clay. You have lots of options!

What do I type in when looking for the tutorial to do this.I am having a hard time finding it.

You don't need a tutorial. Just put the picture down, cover it with a piece of parchment (I tape both down) then start tracing over it with your chocolate! It's that easy. I recommend that you use a parchment cone to pipe the chocolate, because using the plastic bags will result in lines that are flat instead of round. Here is an old thread talking about white chocolate transfers:
