I copied the MIDSECTION diagram (.jpg) off the internet ... and pasted it into my Paint Shop Pro image software. Then is cropped it down to just the tiller arm portion, erasing any unrelated parts that were still showing in the cropped image. Then I added the coloring of the parts, and the part numbers. Then I saved the finished image on my desktop. Then I signed on to my Photobucket account and uploaded the image. Then adjusted the image size so it wouldn't appear too large in my post ... and then simply inserted the internet location of the Photobucket image between the HTML labels for an image like this (

Sounds complicated, but probably only took me 10 minutes from start to finish!
