I know there are 1000+ examples of doing this, but I cannot seem to make it work.

What I have tried:

This is my sample. The first part is just a bit of code proving that there is an image in the first position. This is a sample of what I have tried.

C#

imageList1.Images.Add("pic1", Image.FromFile("c:\\egg\\test\\014.jpg"));
            pictureBox1.Image = imageList1.Images[0];

            listView1.View = View.LargeIcon;
            imageList1.ImageSize = new Size(32, 32);
            listView1.LargeImageList = imageList1;
            ListViewItem item = new ListViewItem();
            item.ImageIndex = 0;
            listView1.Items.Add(item);

I did search and tried to apply what I saw. Plus, read your rules, "4. Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question."

Set the ImageSize BEFORE you add the items: otherwise, it discards all images that aren't exactly right.

C#

imageList1.ImageSize = new Size(32, 32);
ImageList1.Images.Add("pic1", Image.FromFile("c:\\egg\\test\\014.jpg"));

pictureBox1.Image = imageList1.Images[0];

listView1.View = View.LargeIcon;
listView1.LargeImageList = imageList1;
ListViewItem item = new ListViewItem();
item.ImageIndex = 0;
listView1.Items.Add(item);
