If you have a webbrowser control on your form you could take the Images propertynfrom the current HtmlDoument property of the browser. Then you could get the src attribute of each image and load that into the imagelist. I will get some code soon
Here is the code for adding all the images to ImageList1. You can so use that imagelist in your listview
Code: Select all For Each Image As HtmlElement In WebBrowser1.Document.Images
Dim URL As String = Image.GetAttribute("src")
Try
Dim NewImage As Image
Dim ImageStream As Stream
Dim Request As HttpWebRequest
Dim Response As HttpWebResponse
Request = HttpWebRequest.Create(URL)
Response = Request.GetResponse()
ImageStream = Response.GetResponseStream
NewImage = System.Drawing.Image.FromStream(ImageStream)
ImageList1.Images.Add(NewImage)
Catch ex As Exception
MsgBox("Failed to add the image from the url """ & URL & """.")
End Try
Next

sorry i have found i have edited the line :
ImageList1.Images.Add(NewImage)
to :
ImageList1.Images.Add("Picture name", NewImage)
and after we can add the picture with the items with this code :
Dim str(3) As String
Dim itm As ListViewItem
str(0) = "test111" 'First column
str(1) = "aaaaa" ' second column
str(2) = "sssss" ' third
itm = New ListViewItem(str)
itm.ImageKey = "the picture name"
ListView1.Items.Add(itm)
