[Plugin: Shashin] Long caption on photo thumb.. how can I cut it ?

Hello

Is there a way to have a short caption under photo thumb?

see my site : http://www.antoniomalendze.it/galleria/la-famiglia/ for better understand.

Would be great for me to have on one line a caption preview , something like 3 or 4 words followed by … and full caption in the pop up.

thanks for suggestions
