This is an easy to use and attractive grid gallery which is resizable. You can resize the thumbs and you can also resize the main gallery. If you are resizing the thumbs you must make your thumb images match the thumb size specified in the xml. You can make the big image any size you want and the gallery will scale the image to fit within the gallery dimensions, but it is best to make the big image the same size as the gallery. You can add as many menu columns as you want and you can also add a link for the big image.
