Thanks for advices both of you. Actually I wanted to make a new window like amazon.com`s images. They are opened in a new window without flasy effects. It`s like a html with 8 visible images and if you click on 4th one, it is opened in a new smaller window showing the image and you can back and forward to other ones. Kind of image viewer... but I think that JS is for this task rather perl/php/server scripts... Maybe some ready made jQueries codes.
