Remove titles and image count from thumbnails

Hi
I create 2 galleries and then an album
I would like to remove the titles from the thumbnails as you see in the screenshot
also I would like to have a similar hover effect whet the mouse pass over
Can anyone help?

I would like to achieve a similar effect as this site

I am working on a gennesis framework and the foodie theme
Thanks
