I am developing on localhost for PCs not connected to the internet so I need to store jQuery files on localhost

Everything is working fine except jquery image sprites so for example if I have datePicker and calendar will show up it is shown without LEFT and RIGHT arrow to move between months?

My question are:

1. Where to store sprites if my jquery is in folder jquery/jquery.min.js and jquery/jquery-ui.css,js?

2. Where can I download jquery sprites?

Thank you
