Link to Lightbox Image-Group from Menu?

Is it possible to link to the first element of a lightbox-group with data-rel attribute from the WP-Menu? I've tried serveral things (JinMenu Plugin, onclick function) but I failed. Do you have any clues for me? Maybe with Javascript? Or Plugin?

The links are formatted like this:

a id=nomestart class=mobx href=http://www.testurl.at/testbild.jpg data-rel=nomegroupimg class=alignnone wp-image-1829 src=http://www.testurl.at/testbild.jpg//a
