Change "Show Post Title" font/size to Nextgen gallery thumbnail on home page

Hello!

Just like the title says 🙂 See the website under Picture Galleries at the bottom and you will notice what I am talking about. I might have to add code to specify some rules for the change? I have never added code and would not know what to add nor where to add it. I suppose I would like to make the text size and style like that of the Blog titles above it.

Thanks in advance for any and all help!!! This site is great.
