Well, to attach an image...
Bring the errored part to the front of the screen, and hit the little botton on your keyboard called "prt scrn" or something similar. Usually located toward the upper right. Then go to a program such as Paint, or Photoshop, and hit Ctrl+V for paste. Make sure it looks right, then save your image as a gif, jpg, or png. Then come to post your message, and toward the bottom next to Attach File, hit "Choose" and select it. Voila.
