string stFileName = "abc";
string stFullFilePath = Server.MapPath("images/" + stFileName + ".jpg");
System.Drawing.Image i = System.Drawing.Image.FromFile(stFullFilePath);

EncoderParameters eps = new EncoderParameters(1);
eps.Param[0] = new EncoderParameter( Encoder.Quality, 40 );

ImageCodecInfo ici = GetEncoderInfo("image/jpeg");//this line give error, "The name 'GetEncoderInfo' does not exist in current context"


i.Save(stFullFilePath, ici, eps);

These are very simple errors that the dev enviroment tells you how to fix.
You are probably just missing a namespace reference.

Click on the offending word and hover your mouse there, if you have spelled it correctly (capitalization counts!) then a little red underline will appear below the last character, hover your mouse over that and see the options.

If that does not appear, check the help on that command and find out what
namesapce you need to include to use it.

private ImageCodecInfo getEncoderInfo(string mimeType)
{
// Get image codecs for all image formats
ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();

// Find the correct image codec
for (int i = 0; i < codecs.Length; i++)
if (codecs[i].MimeType == mimeType)
return codecs[i];
return null;
}

I hope that is helpful
