This example, it use a rect to show the appearance of pictures-like look. It do look good.

When I try to add real pictures inside, I found it is very hard.
Pls see this http://www.mm3bb.com/
I use img tag to take place of origin svg tag, then the pictures of different size looks very ugly!!

Another try is to use img tag to take place of rect tag. then wired things happen that img tag run out of svg wrap. and it shows in different high, the whole page is ugly too.

I just want to use different size pictures based on the Album example. Any good people can teach me how?
