Gallery Images as links

Using Catch Responsive and i want to have multiple images on the frontpage (static) in a possible gallery format. Thing I would like is a transparency with text to appear over the image when you hover over it and if you click on it takes you to an individual page for that image. If you scroll down past the header images you can see what I'm after http://www.gregklassen.com/ How would I go about accomplishing this? Can you suggest a plugin? Would it be better to place on a page or a post? Thanks
