image zoom

[surfing fox]

Im using this code to access a image,

<img name="rImage" src="https://www.fnmoc.navy.mil/products/WW3/ww3.w.europe.sig_wav_ht.000.gif" width=600 height=600>

Can I change it so it only shows the top corner of the full image? like a zoom in...

wouldnt it be easier to cut the image?
