72833 open new window from thumbnail

I am posting a large photo gallery on a clients upcoming site. I need a javascript that will open a new window when a thumbnail is clicked, the window needs to be a fixed size (lets say width350x height350) or (an automatic resizing of the window to fit the various images would also be cool), it needs a close window button, and I want to disable "right click" to prevent easy stealing of images. Any suggestions about this task or how to make it more effective would be greatly appreciated. (Please Help! Upcoming projects in Perl/PHP/javascripts/ and the search for 0fresh web design ideas will also be posted very soon!)
