Highlight the picture and press ctrl+k.
This will bring up the hyperlink menu. On the left side of the menu choose the second option - it will say something in Korean and in brackets (A).
That will change the right hand side of the box. You want to choose the slide you want (Korean for slide is 슬라이드), choose by slide number (e.g. 슬라이드2). After you have clicked on the slide you want to link to, both the boxes at the bottom right will be available. Click on the left hand side on (확인) to complete your link. The other button (쥐소) is cancel.
I hope that helps.
