This can be used:

Answer 2

In CSS:

img
{
height: 128px;
width: 128px;
}

Answer 3

If you give only one argument to the tag it will automatically calculate the second, but it will always maintain the aspect ratio of the image.

If you need to set the w/h to the same in images with ratio different than 1/1 you'll need to use some javascript to retrieve the height or the width and give the same value to the other argument using JS.
