[Javascript] Changing picture src stretches/squeezes new picture

[Peter Brunone]

Group,

	I have a single image in the center of the page, with a NAME attribute of
"mainPic".  Now I trigger various functions from different clickable links,
that will change the .src attribute of mainPic.  This works fine, but I've
noticed that in Netscape (version 4.x), the subsequent pictures either
expand or contract to the size of the original picture.  How can I prevent
this?

Cheers,

Peter
