In addition to these requests http://drupal.org/node/336240 and http://drupal.org/node/369981, it will be great to have lightmodal width аuto height, to display content without "white space" and vertical scrolling.
If it is possible, the same request for the lightframe.

I have the same problem in D7.
When I set rel = lightmodal[|height:auto;]
then there still stays minimal height 250px in ligthbox, although content has just 100 px height.
