Display list of images from internet

If I have an array of urls which link to images, how can I list them as thumbnails in my application?

is your question about the array part, picturebox part, or the resize part?

to assign a picture box a url, use this code:

Code:

---

Me.PictureBox1.ImageLocation = "http://someaddress/somepic.jpg"

---

to resize an image, you can use this:

Code:

---

Public Function ResizePic(ByVal getPicAddress As String)

        Try
            Dim picBox As PictureBox = Form1.PictureBox1 'pic to resize
            Dim pSizeMode As PictureBoxSizeMode = PictureBoxSizeMode.CenterImage


            picBox.Image = Nothing
            picBox.SizeMode = pSizeMode
            If System.IO.File.Exists(getPicAddress) Then
                Dim imgOrg As Bitmap
                Dim imgShow As Bitmap
                Dim g As Graphics
                Dim divideBy, divideByH, divideByW As Double
                imgOrg = DirectCast(Bitmap.FromFile(getPicAddress), Bitmap)

                divideByW = imgOrg.Width / picBox.Width
                divideByH = imgOrg.Height / picBox.Height
                If divideByW > 1 Or divideByH > 1 Then
                    If divideByW > divideByH Then
                        divideBy = divideByW
                    Else
                        divideBy = divideByH
                    End If

                    imgShow = New Bitmap(CInt(CDbl(imgOrg.Width) / divideBy), CInt(CDbl(imgOrg.Height) / divideBy))
                    imgShow.SetResolution(imgOrg.HorizontalResolution, imgOrg.VerticalResolution)
                    g = Graphics.FromImage(imgShow)
                    g.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
                    g.DrawImage(imgOrg, New Rectangle(0, 0, CInt(CDbl(imgOrg.Width) / divideBy), CInt(CDbl(imgOrg.Height) / divideBy)), 0, 0, imgOrg.Width, imgOrg.Height, GraphicsUnit.Pixel)
                    g.Dispose()
                    'get format

                    Dim NewPicAddress As String = CurDir() & "\images\" & getPicAddress.Substring(getPicAddress.LastIndexOf("\") + 1)

                    Debug.Print(NewPicAddress)

                    NewPicAddress = getPicAddress.Remove(getPicAddress.Length - 3, 3)
                    imgShow.Save(NewPicAddress & "bmp", System.Drawing.Imaging.ImageFormat.Bmp)
                    'now delete old one
                    Form1.PictureBox1.ImageLocation = NewPicAddress & "bmp"

                Else
                    imgShow = New Bitmap(imgOrg.Width, imgOrg.Height)
                    imgShow.SetResolution(imgOrg.HorizontalResolution, imgOrg.VerticalResolution)
                    g = Graphics.FromImage(imgShow)
                    g.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
                    g.DrawImage(imgOrg, New Rectangle(0, 0, imgOrg.Width, imgOrg.Height), 0, 0, imgOrg.Width, imgOrg.Height, GraphicsUnit.Pixel)
                    g.Dispose()
                End If
                imgOrg.Dispose()

                picBox.Image = imgShow

            Else
                picBox.Image = Nothing

            End If



            Return True
        Catch ex As Exception
            MsgBox(ex.ToString)
            Return False
        End Try



    End Function

so, you would have an event fire (maybe, onload, or click event) that would call the above function.
if you have any questions, let me know

the only thing you would need to change is this bit:

vb Code:

'change this to a folder you want.  right now, this is saying it will save the new image in folder called "images" in the current directory
 
                    Dim NewPicAddress As String = CurDir() & "\images\" & getPicAddress.Substring(getPicAddress.LastIndexOf("\") + 1)
 
 
'this will save the image as a bmp
                    NewPicAddress = getPicAddress.Remove(getPicAddress.Length - 3, 3)
 
 
                    imgShow.Save(NewPicAddress & "bmp", System.Drawing.Imaging.ImageFormat.Bmp)
          
                    Form1.PictureBox1.ImageLocation = NewPicAddress & "bmp"
