Display images resized to browser window

Hi

I’m trying to find an image viewer similar to Lightbox, Shadowbox etc that allows the displayed image to resize automatically to the browser window and also prevent the “Save image” option when you right click on it.

Does anyone know of a plug-in that does this?

I like the presentation style of the image appearing over the website rather than opening a new page. I’ve tried many of the JavaScript based image viewer plug-ins available. Some will resize the image on the fly as you change the size of the browser window and some will prevent you from easily saving the image with the right click. However, none of the plug-ins I’ve tried so far allow you to do both. Is there a technical reason for this? Or is there a simple bit of code that can be changed? (I’m not a coder but I’m a dab hand with copy and paste.)

Thanks.
