Is it possible to show the images that have been ranked/voted better??

how?

Bye

Yes, it is.

• Most voted: http://www.zenphoto.org/documentation/Zenphoto/_template-functions.php.html#functionprintPopularImages
• Best voted: http://www.zenphoto.org/documentation/Zenphoto/_template-functions.php.html#functionprintTopRatedImages

But i dont understund where should i paste the code...

do i have to create a new file like "mostvoted.php" and place it in my default theme directory??

Please explaine to me very carefully

No, you just need to paste that functions on one or all of your theme files where you want them to be shown.
For example for the most voted 10 images use this:``

And if i want it in a separate file..

like: www.mysite.com/gallery/mostviewed.php ???

You could do that, too. Place that file in your theme's folder and call it with www.yoursite.com/zenphoto/index.php?p=mostviewed if you do not have modrewrite and if you do with www.yoursite.com/zenphoto/page/mostviewed.
