We used wpmudev multisite subscribe and it finally worked. No free plugins worked. I am not sure what the problem is, but for now that the only plugin we could find.

For now we use a separate lightbox plugin instead of the lightbox option with SU.

If you use the gallery or slider option, just select to link to media image. If you have another lightbox plugin it will display using that. Then you can use that plugin easily configure.

Simple Lightbox and Lightbox Plus Colorbox work well with SU.
