A Yii virgin here 
I’ve got some images, css and js scripts my site will need to use but not sure if there is a specific place they should be in or if i just use my own structure.
ROOT
----assets
----css
----framework
----images
----protected
----scripts
Is the above ok? I’m using CClientScript to add the scripts and css as an when they are needed.
That’sa absolutely standard and correct structure.
I usually put the framework in the previous folder, so that it will not be web accessible, but that is a simple question of habit.
Ah, That’s ok then, Just didn’t want to break or not use a standard already built it.
cheers.
Know the rules before breaking them. 
If you’ve read about naming conventions in the Yii guide, then stick to that. At least until you know what the rules are.
When you create a webapp using yiic, everything’s laid out for you.
But ask anytime if you have doubts.
