captions and auto start portfolio slides

HI, the captions on my portfolio gallery pix don’t appear. Is it possible to make this happen? I would like viewers to see who the work was done for.
So far, I only have made a portfolio gallery for Invitations if you would like to take a look.

Also, on this page and the other pages which have sliders, the slide show does NOT automatically begin, even though i have set it to autoslide. It starts to work if I manually select the arrow or button, but I want it to be automatic so viewers won’t get frustrated. I found this to also be true on your sample site.

I am on a Mac, using FF & Safari
