You use elm_photo ?
The grid resize the item, then if you do not want increase the size of the
photo, this is the job of the item. Maybe you can try
elm_photo_fill_inside_set(ph, EINA_TRUE);
see:
http://trac.enlightenment.org/e/browser/trunk/TMP/st/elementary/src/bin/test_photo.c
> Secondly, I want this horozontal images has no (or very small) 'panding'

I think the padding you see is in the items and not between.

> Lastly, How can i hide - automatically displayed - scrollbar?

you can do this in elm_scroller, see Elm_Scroller_Policy.

You means the scrollbar disapear while you scroll ?
