scrolling through listbox item's with button's

hello.

within the userform contacts, when mouse-over the image two buttons are shown.
I want when one of these buttons are it displays the next image. the names of all images for the contact are loaded in userform1 listbox. also change the name of the label1.caption.

The part im having trouble with is knowing where the current picture name is loacated within the listbox.

cheers

on a side note, if insted of using a picture object i use a activex picture viewer thing. Can i play movies within the same object as being used for the pictures.
