Image gallery

[mvlcek]

Now I see those gallery and put it in my page, but why those images open in new window not like in the demo/examples

What do you mean with "open in new window"? Can you give me a link to your site?
Some gallery types (cycle, s3slider, supersized) are directly embedded in the page, while for some (fancybox, prettyphoto) a gallery of bookmarks is displayed, which on click opens a "dialog window" (not a real browser window/tab) with the larger image.

(if you have javascript switched off, you will be directed to another page with the larger image instead of seeing the "dialog window").
