Image Viewer Problem

I am new to .Net currently i am using vb.net 2005, I am i am creating an
image viewer that should display single and multiple Tiff images.
I am using a panel and picture box to create an image viewer.
I have created that to show only single tiff image.
But i need to show the images one after one if the tiff image has multiple frames.
I have counted the multiple tiff page frames using following code

Code:

Panel1.AutoScroll = True
ImageViewer.Image = Image.FromFile("C:\Documents and Settings\Administrator\Desktop\test202.tif")
ImageViewer.SizeMode = PictureBoxSizeMode.StretchImage

Dim MasterImage As Image = ImageViewer.Image
Dim oDimension As New FrameDimension(MasterImage.FrameDimensionsList(0))
Dim FrameCount As Integer = MasterImage.GetFrameCount(oDimension)

The above code gives the no of tiff pages

but i don't know how to show the frames one after one in the picturebox

Can you have solution in VB.Net or in C#.net for my problem

foreach (ImageCodecInfo codec in codecs)

ici = codec;

}

//Create a collection of encoder parameters (we only need one in the collection)

EncoderParameters ep = new EncoderParameters();

//We'll save image with QualityPercentage as compared with the original

//Create an encoder parameter for quality with an appropriate level setting

ep.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, (long)QualityPercentage);

//Save the image with a filename that indicates the compression quality used

string newFileName = FileName.ToLower().Replace(".tif", "_Quality_" + QualityPercentage + "%.tif");

bm.Save(newFileName, ici, ep);
