Image Alignment (left or right) is ignored in the magnolia samples templates due to the fact that main.css is missing a class for "left" and "right".

Solution: Copy the .contentImage_right and .contentImage_left classes in main.css and rename then .right and .left - ie..

.contentImage_left {
float: left;
padding-right: 20px;
padding-bottom: 10px;
}
.left {
float: left;
padding-right: 20px;
padding-bottom: 10px;
}

.contentImage_right {
float: right;
padding-left: 5px;
padding-bottom: 10px;
}
.right {
float: right;
padding-left: 5px;
padding-bottom: 10px;
}
