Thumbs down To not make a random number appear twice

I have made this application where theres a tlistview whit image destinations in it.

Then i got a timer to shift the picture.

then ive addet a random function to shuffle through the picture.

now what i want to happen is that the same picture dont get shown twice.

So what i tried was to put the number of the picture in another tlistview and make a "While do" to check if randomly generated number is shown in the list.

this is the code ive tried using.

randomnr := random(listview1.Items.Count -1);

x := 0;

While x<listview2.Items.Count - 1 do
begin

if listview2.Items[x].Caption = inttostr(randomnr) then
begin

randomnr := random(listview1.Items.Count -1);

x := 0;

end;

x := x +1;

end;

item := listview1.Items[randomnr];
form2.image1.Picture.LoadFromFile(item.Caption);

listview2.Items.Add.Caption := inttostr(randomnr);


All help is apreciatet

Best regards,
Darkyere
