Hi and welcome to the forums.

How about the help files? MSDN?

Resources for learning C#
OpenFileDialog
ListView

I went trough them but i can find any thing that can help me

The links I posted contain plenty of resources for learning and all the information you would need to implement what you require. Is there a specific problem within the implementation that you are having?

Sounds like you need to learn the following:
Using the OpenFileDialog
Opening a file (either as a file, or using the Bitmap/Image .FromFile() function)
Create a thumbnail from an Image object
Use images in listviews

Start learning each of those items and you'll be able to put them together yourself.

HI thanks nukefusion this is Wat i got But i Don`t know how to get the
listview to show the files/open them.

OpenFileDialog MyDialog = new OpenFileDialog();
            MyDialog.Multiselect = true;
            MyDialog.Filter = "JPEG files (*.jpg)|*.jpg|All files (*.*)|*.*";
            MyDialog.RestoreDirectory = true;
            MyDialog.Title = "Add Files";
 
 
 
            Stream myStream = null;
 
            if (MyDialog.ShowDialog() == DialogResult.OK)
            {
                try
                {
                    if ((myStream = MyDialog.OpenFile()) != null)
                    {
                        using (myStream)
                        {
                            // listView1.??????????????????????? 
                        }
                    }
                }
                catch (Exception ex)
                {
                    MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
                }
            }
 

I also tried getting the directory and then use it in the picbox image location
it worked but its mad because you have to get all the directories of the files you selected and then use it in the picbox.And if you select to many or to few you get an error. saying Value out side array.

I would use the ImageFromFile() function on the Bitmap class to open the jpeg files.
Then make a copy of the object
Then close the original object (releases the file)
Then assign it to the listview
