The automatic formatting on this forum makes it hard sometimes. I believe initially you were trying to link a picture to your computer:
hyper text transfer protocol ://c/Users/BFPARTS23/Pictures/IMG_3805.PNG
You need to attach the image to the forum (which you did) or upload it to a hosting site and then link here. I use my own webspace which I rent on shared servers for $100/year. It keeps the links to all my pictures stable as long as I keep the domain registered correctly.
By the way, did you ever figure out what happened to your trailer?
