So far I think one of the javascript library call Highside is very useful for us to use.

Highside is free for a personal website, a school site, your family's photo album or a non-profit organisation.
For Redistribution:
You are allowed to distribute Highslide JS with non-commercial packages given that you fulfill two conditions:

• Emphasize to your users that Highslide JS is not free for commercial use. You can do this on your download page or when your users activate Highslide in your application.
• Provide a link back to this web page in the same location.
