I want to create offline Play list for Bmps in c# forms

Question

In my application I want to Create Offline Play List in c#.
I am Browsing (or)Drag and drop  images from system. After that I am adding Start date, start time , end date, end time , and stay time.
It is possible when i am right click on the first list view a context menu strip will be uppered and it contains add option when i click on that new form will be opened it contains the date and time pickers for adding date and time , stay time. After selecting all this when i am clicking on ok button it will add the all the details in 2 nd listview. when i enter a name in text ox and press save button the items in the list view will be saved in a note pad.
when i browse that file automatically all the detailes will be loaded into list view 2 and the respected image swill be displayed in list view 1.
when i click on the play button another form will be opened it contains only a picture box. all the images will be displayed as a slide show in it.
My program works perfect in Browsin case.But for the Dra and drop case and  for the re adding case it will fails.
Re adding case means if the user wants to add the same image in list view one multiple times in listview 2 it will fails.
And another condition is If firstly user added 20 images in list view 1 and after that he starts adding into list view 2 in such case also my program fails can any one help me regarding these errors.
