i am trying to implement the imageloader in my project so that i can load images faster from online folder
i am using following code, but the images load at the rate of 1 image per second. Although i have reduced the individual image size to 200kb and there are only 5 images. Can someone guide me where i need to make change in my code to implement bitmapasync

Sub loadlistview
    Dim Table As List
    Dim p As JSONParser
    Dim res As String
    Dim j As HttpJob
    Dim m1 As Map
    j.Initialize("", Me)
    j.Download("http://saeedhassan.atwebpages.com/con.php")
    Wait For (j) jobdone (j As HttpJob)
    If j.Success Then
        res = j.GetString
        Log(res)
        p.Initialize(res)
        Table = p.NextArray
        For i = 0 To Table.Size-1
            m1 = Table.Get(i)
            j.Download("http://saeedhassan.atwebpages.com/images/"&m1.Get("contactname")&".jpg")
            Wait For (j) jobdone (j As HttpJob)
            If j.Success Then
                'Wait For (ImageLoader.LoadFromHttpJob(j, 500dip, 500dip)) Complete (bmp As B4XBitmap)
                B1 = j.GetBitmap
            End If
            clv2.Add(CreateListItem(m1.Get("contactname"), m1.Get("areacode")&m1.Get("phonenumber"),clv2.AsView.Width, 80dip), m1.Get("contactname"))
            
        Next
    End If
    
    
End Sub
Sub CreateListItem(Text1 As String,Text2 As String, Width As Int, Height As Int) As Panel
    Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0, Width, Height)
    p.LoadLayout("CellItem")
    Label1.Text = Text1
    label2.Text = Text2
   
    ImageView1.Bitmap = B1
    
    Return p
End Sub

I guess that it takes around 1 second to download each image. BitmapsAsync will not make it faster and is actually not really relevant here.

You can make it faster by downloading the images in parallel as in the GridExample: https://www.b4x.com/android/forum/threads/b4x-bitmapsasync.119589/
