It's possible to specify the image max. width/height in the system
preferences (see admin menu->configure->system preferences). All images
embedded in the article text will be resized accordingly. When embedding an
image into the article text you can also specify custom width/height that
overrides the system preferences.
If you want to display article images that were not embedded in the article
text by using the template language you can specify the width/height in the
image URL:
{{ url options="image <image_number> width <width> height <height>" }}
