If I want to post a picture, is the only way via a link?
Yes, although you can make it display by putting the [img] fore and aft of it, with the / in the 2nd one.
(if I actually post both of them here in full, they won't show in the text.).
If you post your pics to an image provider, they are free and easy.
I use www.postimage.org
you don't need to sign up, just upload and grab the link and post it here.
Don't forget to save the link, it may be useful later.
P.S. Soap makes a good lubricant for tap mechanisms, and also for preventing leaks.
Roll your tap threads in soap and they will never leak either.
If you moisten the soap first ...
