What you will still need to check for is that no other plugins are loading Jquery as well. If they don’t load it correctly then you could have two copies of the same thing running.

Exactly! This is what is happening.
WP is loading 1.7.2 locally and Nivo is loading 1.5.1 from Google, simultaneously.

I have removed line 32. tested and it works fine with 1.7.2 locally.
The next step is to make WP load jQuery 1.7.2 from Google.

Many thanks!
