Mati is a professional jQuery image gallery that I've created as an homage to my little niece Matilde. It's a grid-based image gallery that allows you to navigate through the image sets and view the full-size image preview. It's free. The only thing you should do is to add an image preloading routine to improve performance. I hope you find it useful.
