Primoz....he is requesting that the pics be pasted on top of each other rather than side by side. Do it however you wish buddy....but in case you were wondering....in order to get the pics to follow each other going vertical all you need to do is:
(1) paste a pic
(2) then hit your "enter" key
(3) paste the next pic
(4) repeat
(I usually hit the "enter" key twice after pasting a pic to give it a msall space in between the pics)
But do it however you wish brother....we're all thankful for the countless pics you post on a daily basis
