Link thumbnails to different gallery lightboxs

Hi,

First off the plug in is great it is exactly what I have been looking for, for a good while now.

I have a couple of questions though: the first is, is there a way that I could link the thumbnails to different galleries. I am building a website for my brother hunthistoricaljoinery.com and what I wanted to do is in the our work page to have a mosaic gallery that has 4 to 5 images that each represent a job he has completed and that when clicked on it would open a lightbox with 3 to 4 images of a particular job. I have to say that I am a complete newbee and as such have no idea if there is this feature in the plug in or some other work around.

The second thing that I was wondering is: when I open the page (our work) for the first time it often seems as though the gallery overspills onto the footer and the size of the footer gets extended in height. I think that perhaps it is something to do with the theme I used to begin with “Theseract” ( I told you I was a newbee ?? ) as I had an issue with giga slider showing space above and below it which a very helpful member of the support forum helped me with a piece of code to overwrite ( I think she mentioned that there might be an empty paragraph somewhere or something like that.

Anyway I would really appreciate a bit of help as I have no Idea how to solve this on my own

Thanks in advance for any help
