A very useful and time saver plugin you persons have developed. I am using it at http://www.photofilms.in. I have uploaded around 5 images on http://www.photofilms.in/product-shoot/ and configured supersized as:
Center the background vertically: on
Center the background horizontally: on
Fit image: Fit Always
Now, there is an issue when I view pages on 4:3 kind of computer display, two of the starting images are not well scaled whereas rest of the images are showing beautifully.
