save for web

Hello, Adobe Photoshop has a feature called 'save for web' which I use a lot because, well, because it seems to do it all for me.

What is the Photo Paint X4 equivalent and, if I need to select any parameters, what would you suggest to get optimum images for web pages? 

(I realise as I am writing this that 'optimum' opens up all sorts of questions!)

Thanks

Chris
