Hey. Someone please tell me how can i do to someone press a picture than open new window and show picture in bigger sizes. like it show picture i added. thanks

Please see the FAQ entries How can I create a thumbnail image that is linked to the full-sized image? and How do I create a link that opens a new window?

thanks. i readed and i know now...i only dont know how to make window smaller when someone click the small image.

and what is this return false"> at the end?

This prevents the browser from processing both the normal link and the JavaScript event handler that replaces the normal link when JavaScript is available.

How do you mean "make window smaller"? The pop-up window?

yes look my code how i do:

<a href="www.shrani.si/picureblabla" target="popup" onclick="window.open('example.html', 'popup', 'width=100,height=50'); return false">View Foo</a>

i used width 100 and height 50 and still same window (big one)

Looks right to me. Maybe you have configured your browser not to allow sizing of windows?

Maybe it won't be extly 100x50. A window can't be below a certain site, but it should be small.

Note thatandare not the same, and do not refer to the same thing.

True, but the JS for the window size looks OK AFAICS.
