Hi,

How can i resize 4 images and place them in equal sizes in 1 file.
I have 400 + Pictures in a folder i want a script that can make these just 100 files by resizing them smaller in equal shares and place 4 images in 1 file and name them 1,2,3,4.jpg.

So when opened i can see 4 images in 1 mspaint or windows Photo gallery.

Regards
sharath

I'm not aware of any way to do this in pure VBScript (.vbs) or CMD Scripting...you would need to call out to an external application or library.

You could do it in C# or VB.Net Express, both of which are FREE from Microsoft:

Here is a quick knock up using VB.Net 2005 Express:
http://www.microsoft.com/express/2005/download/default.aspx

Imports System.IO
Public Class Form1
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim thumbSize As New Size(250, 250)
        Dim bmp As New Bitmap(thumbSize.Width * 2, thumbSize.Height * 2)
        Dim g As Graphics = Graphics.FromImage(bmp)
        Dim folder As String = "c:\"
        Dim FileNames As New List(Of String)
        Dim newFileName As String
        Dim counter As Integer
        Dim counter2 As Integer
        Dim pb As New PictureBox
        pb.BorderStyle = BorderStyle.None
        pb.SizeMode = PictureBoxSizeMode.Zoom
        pb.Size = thumbSize
 
        For Each fi As FileInfo In New DirectoryInfo(folder).GetFiles("*.jpg")
            counter2 = counter2 + 1
            pb.Image = New Bitmap(fi.FullName)
            Select Case counter2
                Case 1
                    pb.DrawToBitmap(bmp, New Rectangle(0, 0, thumbSize.Width, thumbSize.Height))
 
                Case 2
                    pb.DrawToBitmap(bmp, New Rectangle(thumbSize.Width, 0, thumbSize.Width, thumbSize.Height))
 
                Case 3
                    pb.DrawToBitmap(bmp, New Rectangle(0, thumbSize.Height, thumbSize.Width, thumbSize.Height))
 
                Case 4
                    pb.DrawToBitmap(bmp, New Rectangle(thumbSize.Width, thumbSize.Height, thumbSize.Width, thumbSize.Height))
                    counter2 = 0
 
 
            End Select
 
            counter = counter + 1
            FileNames.Add(counter.ToString("00"))
 
            If FileNames.Count = 4 Then
                newFileName = Path.Combine(folder, String.Join(",", FileNames.ToArray) & ".jpg")
                g.Dispose()
                bmp.Save(newFileName, System.Drawing.Imaging.ImageFormat.Jpeg)
 
                bmp = New Bitmap(thumbSize.Width * 2, thumbSize.Height * 2)
                g = Graphics.FromImage(bmp)
                FileNames.Clear()
            End If
        Next
 
        If FileNames.Count > 0 Then
            newFileName = Path.Combine(folder, String.Join(",", FileNames.ToArray) & ".jpg")
            bmp.Save(newFileName, System.Drawing.Imaging.ImageFormat.Jpeg)
            g.Dispose()
        End If
 
        MessageBox.Show("Done!")
    End Sub
 
End Class

Yeah...download VB.Net 2005 Express from the link I gave.  ...or you could download the newer VB.Net 2008 Express.  Either would work and both are free.  All you have to do is register it once you have it installed.  It's pretty easy.

Then you start with a "WinForms" Project (Windows Application) which gives an app with just one default form (Form1).

Right Click the Form and select "View Code".
Paste the code above over the ENTIRE default code.

Change this line so it reflects the folder you want to work with:

    Dim folder As String = "c:\"

Run the application...

You need to add a Button (Button1) to your Form.
