You can drag the edges of the background as well as the image area to whatever size you desire. To get into this 'editing mode', you first need to hold down the ctrl key and click on the grey area outside the black background.

Thank you, the resizing tips helped, I got it dialed in.

Bruzer, thanks for your help but I never could locate the lightbox index file. It's very strange isn't it? Lightbox definitely created it, but it never appeared in XP. I can only assume it is something specific to my PC or OS.

Must be something Stan, I just don't know what to tell you. lol
Well good luck.
Stan have you tried the option of inserting into html, if so then you may possibly have the data and engine folders in your website directory on your HD.
