Hi, found this on the net : http://www.users.globalnet.co.uk/~leonid/posture_start.htm
I found it helpful and interesting.
Can any 'more experienced' players comment if the advice given is good? (worrying here if I would be following correct advice or not).
I thought I'd post the link as I have noticed that a few beginners like me were wondering where to find photos of correct posture and this site has lots of photos.
Many thanks

Just wanted to add:
I found the 'menu page' of this site and it has links to many other helpful pages, here it is:

Lots of other useful stuff on the sight too

I was going to suggest violin masterclass too! The previous website didn't tell you where the index finger should be placed. The index finger is important in determining dynamics. Bow grips vary slightly among everybody. What's important is that the hold is comfortable for you.
