A simple gallery with one really cool feature: ZOOM!
A custom template for FooGallery which allows your visitors to magnify your images with a magnifying glass-like effect.
Like other FooGallery templates you can customize the image size, border styles and shapes. With ZOOM! You can also customize the lens size, lens border, shadow depth. You can also set your thumbnails to have a grayscale or blurred effect either on load or on hover. Blur/grayscale only effects the thumbnail, so that when you look through the magnifying glass you still have a sharp, crisp, and full-color image magnified.
