automatic image handling for Drupal 7.x

I cannot get the automatic image handling work for me.

I am using Drupal 7.x, so I don't have most of the modules the Lightbox2 supports (Image, Inline, Flickr, Acidfree Albums, Image Assist, Embedded Media Field and CCK Imagefield) because they are still versions 6.x. I only have Embedded Media Field 7.x and CCK 7.x.

I am not sure if I miss something, or if this feature is not working with Drupal 7.x yet? (I have searched the issue list but could not find this issue with Drupal 7.x)

Thank you very much for any help!
Pauline.
