Images as Thumbnails

Hello,

I am trying to get create a wordpress page that uses the shadowbox plugin for images but my main problem is getting the images to display neatly on the page it is very hard to get them all to display neatly with the WYSIWYG Editor. I pretty much want a table layout but something that doesnt need coding as this will have to go to a client that doesnt no code.

Is there any Plugin that does this for you.

Thanks
