Hi,
with imgur, you can embedd the image easily in your post,
right click on the imgur image itself, copy the image url, and in the post, paste it using the image tag ( from the toolbox of the message)

now, onto the problem itself
you get the position once, when you enter that state, and so if the object has moved, then of course the values differs.
Could it be also a problem of hierarchy and local/global position mess?
Bye,
Jean
