force my pictures show the same width and the same height

[win8win]

be default,it will show the same width or the the same height,how to make pictures show the same width and the same height?
any suggestion,

Thanks

one way is to make the original pictures all in the same width and the same height, but the pictures are too many,

is there other simple way by setting ,a little twist would be ok.

figured out,it is easy,

first ,add a <div class="bestnewproduct"> the code showing images</div>

second,add the following code at the bottom of stylesheet.css,

.bestnewproduct img
{
width: 182px;
height: 200px;
}
