I need a page showing the images in different tabs using the "image gallery"

Like this:

--- when firstly open the page:

(tab1)(tab2)(tab3)

showing gallery1

---- when click on tab2 :

(tab1)(tab2)(tab3)

showing gallery2

---- when click on tab3 :

(tab1)(tab2)(tab3)

showing gallery3

When click on any of the tab button, it correctly shows the gallery inside the tab.

But the problem is: when firstly open the page, it didn't show the gallery1 in the tab1.

How to resolve this?

The website is not online, it\'s on my server.

But I decide to use other ways to display my images. thanks any way
