Gary, there are two ways to add pictures. If you use "Quick Reply" you have to go back in with "Edit". When in edit or "Post Reply" or "Post New Topic" you will find "Attach Files" and "Upload Photos" at the bottom of the page. That will open a new box where you select "Browse" to locate your photo(s) , then select "Upload".
I don't find my traveler that hard to adjust. I prepare for a tack by first moving the "lazy" windward stop. If I want to further adjust when it has pressure on it then I just head up a little to release it. Granted, not good for racing. I sail on big water, first Lake Erie, now Gulf of Mexico, so tacks are not too frequent.
If I was going to an adjustable track it would definitely be a Garhauer. And as Steve points out they would drill it to match.
