Lightbox on particular images

hey…

i’m using jetpack and its great carousel-plugin for my website.
but when i insert solo images and choose link to “media-file”, there is no lightbox.

can anybody help me with this problem?

i hope you understand my poor english 😉

i want to use the integrated lightbox-plugin of jetpack.

when i generate galeries with the wordpress-mediamanager, everything ist ok. the lightbox-plugin is great and i’m very happy with it.

but when i insert a single picture into a post and link the picture to the media-file, there is no lightbox.

example:
gallery: http://zeltlager.cvjm-ebersbach.yourweb.de/2013/08/10/spiel-des-jahres-2013-heutige-position-feld-810/ => everything is ok
single picture: http://zeltlager.cvjm-ebersbach.yourweb.de/2013/09/26/zeltlager-nachtreffen-am-17-10-2013/ => no lightbox

can anybody help me with this problem?

greetings from germany!
