Inserting images into Mysql database:

First create a database column with datatype image

Now
use this code

HttpPostedFile img;

img = FileUpload.PostedFile;

Byte[] bt = new Byte[img.ContentLength];

img.InputStream.Read(bt, 0, img.ContentLength);

when you use the insert query for the column with image datatype insert the value bt!

Hope this helps you.......

You can use this code sample

public class DataAccess
{
    private string _strConn = 
        @"Driver=   {MySQLODBC 3.51 Driver};SERVER=localhost;DATABASE=test;"; 

    private OdbcConnection _objConn;

    public DataAccess()
    {
        this._objConn = new OdbcConnection(this._strConn);  
    }
    // This function adds the Images to database


    public string addImage(byte [] buffer,string extension)
    {
        string strSql = "SELECT * FROM File";
        DataSet ds = new DataSet("Image");
        OdbcDataAdapter tempAP = new OdbcDataAdapter(strSql,this._objConn);
        OdbcCommandBuilder objCommand = new OdbcCommandBuilder(tempAP);
        tempAP.Fill(ds,"Table");

        try
        {
            this._objConn.Open();
            DataRow objNewRow = ds.Tables["Table"].NewRow();
            objNewRow["Extension"] = extension;
            objNewRow["Data"] = buffer;
            ds.Tables["Table"].Rows.Add(objNewRow);
            // trying to update the table to add the image

            tempAP.Update(ds,"Table"); 
        }
        catch(Exception e){return e.Message;}
        finally{this._objConn.Close();}
        return null;
    }
    // This function to get the image data from the database


    public byte [] getImage(int imageNumber)
    {
        string strSql = "SELECT * FROM File";
        DataSet ds = new DataSet("Image");
        OdbcDataAdapter tempAP = new OdbcDataAdapter(strSql,this._objConn);
        OdbcCommandBuilder objCommand = new OdbcCommandBuilder(tempAP);
        tempAP.Fill(ds,"Table");

        try
        {
            this._objConn.Open();
            byte [] buffer = (byte [])ds.Tables["Table"].Rows[imageNumber]["Data"];
            return buffer;
        }
        catch{this._objConn.Close();return null;}
        finally{this._objConn.Close();}            
    }
    // Get the image count


    public int getCount()
    {
        string strSql = "SELECT COUNT(Data) FROM File";
        DataSet ds = new DataSet("Image");
        OdbcDataAdapter tempAP = new OdbcDataAdapter(strSql,this._objConn);
        OdbcCommandBuilder objCommand = new OdbcCommandBuilder(tempAP);
        tempAP.Fill(ds,"Table");

        try>
        {
            this._objConn.Open();
            int count = (int)ds.Tables["Table"].Rows[0][0];
            return count;
        }
        catch{this._objConn.Close();return 0;}
        finally{this._objConn.Close();}
    }

}
