    I dont know where to start on this so thought of posting it. Basically, I have to address all the following tasks.

    We have a large number of pictures which we send out to our customers on a regular basis. They get over sized and dont upload properly.

    I plan to make an application which re sizes and emails pictures.

    1) Select pictures with similar names ( first 5 digits) from some selected folder. May be on a button click.

    2) Re-size them to 200KB-400KB.

    3) Upload and Email them (Using Exchange). Email address is entered by user. Usually there would be around 20 pictures attached per email.

    4) Save those re-sized pictures to some drive.

    5) Delete the non-re-sized pictures which were selected.

    Could you please guide me little bit on what controls can I use?

    I have written a small appliction in uses a couple of Telerik Win Form controls, this will compress the size of images and currently I have defined three parameters to compress

    a) Percentage of Size
    b) Final Width
    c) Final Height of Image

    It has two facilities
    a) Select a folder, then it creates a sub folder "Optimized" and the optimized images are save there
    b) Monitor a folder , then whenever a image is created i tne folder and application is running a optimized image is created in sub folder

    You could download the executable from

    It will require dotnet Version 4.0


    In case that works for you  I would give the source code

    Hello Sanjay,

    Thanks for the reply. I have download and ran the exe file.

    It does pretty much what I want (Excluding the auto email upload option).

    I like the application however I found out

     "Select the folder" doesn't work so I wasn't able to use process files button.

    I would surely love to use the application code to make it to the level that I can customize it to what I want.

    I would also want to convert it to Web application.

    Could you please post it? or email it to

    The main code

        reDuce = Val(Rval) / upWidth
    ElseIf Val(Redty) = 3 Then
        reDuce = Val(Rval) / upHeight
        MessageBox.Show("Enter the  Final Size of Image", "Image Optimizer")
        Exit Sub
    End If
    newHeight = upHeight * reDuce

            '   Point atPoint = new Point(100, 100); //The pixel point to draw the watermark at (this example puts it at 100, 100 (x, y)).
            Dim brush As SolidBrush = New SolidBrush(color)
            newGraphic.DrawString(WaterMark, font, brush, atPoint)
        End If
