Start with this:
img height=400 smc=the image location
the height=400 controls the size of the image. Do a preview.
If it is too large use a number less than 400.
If it is too small, use a number larger than 400.
Do another preview to see if it looks like what you want.
If it is good, post.
I made a formatting mistake: instead of smc, use src.
