One word of warning : be very careful! Remember that you have absolutely no control over the size of the browser window that the user is using to view your web page, and if you hide iframed content by setting overflow:hidden you run the risk of the user being able to see only a partial page and not being able to scroll to see the rest of it.

I would like to see more control over this available through options. My case in point is displaying an HTML page set to precise dimensions. I want to insure that scroll bars never appear, in either dimension, and that Shadowbox-js makes no attempt to resize.
Just to be clear, I would set the body for the page to specific dimensions, like 850x560, then use those same dimensions as the height and width settings for that Shadowbox. It would be my responsibility to make sure the content fit in the space.
I was able to get this effect by modifying shadowbox-iframe.js as suggested above. I don't think that is a satisfactory solution, as it affects all instances.
If you want a custom script designed to your specific situation, build it your damn self. Why are you entitled to have someone spend hundreds of hours making every option conceivable easily tweakable by lazy piggie-backers who are ungrateful for all the hard work already done on this project? How bout making a hefty donation to the developer before voicing off how <strong><em>YOU</em></strong> feel the script should function regardless of the unpaid man-hours that would have to go into it.
