The following will undoubtedly need some tweaking, but it should be close:

int m_itemCounter = 0;
bool TopOfList { get { return m_itemCounter == 0); } }
bool EndOfList { get { return m_itemCounter >= listBox.Items.Count; } }

private List<string> GetNItems(int count)
{
    List<string> results = new List<string>();
    int stop = Math.Min(count, this.listBox.Items.Count - m_itemCounter);
    for (int i = m_itemCounter; i < stop; i++)
    {
        results.Add(this.listBox.Items[i]);
    }
    m_itemCounter += stop;
    return results;
}

you could cheat and have a hidden control containing all pictures, create a start point variable to point to pic 1 then display in another listbox 1 - 10 of the hidden one, when user clicks next increase the start point variable to 11 and display 11-20 and so on, obviously clearing listview first.

I know it messy and I apologize before i get shot down in flames, depending on my target audience it would be one way.
