//Method
public Bitmap GetPhoto(byte[] photoBits)
        {
            if (photoBits != null && photoBits.Length > 0)
            {
                using (MemoryStream stream = new MemoryStream(photoBits))
                {
                    return new Bitmap(stream);
                }
            }
            else
            {
                return null;
            }
        }
cmd = new OleDbCommand();
cmd.Connection = con;
cmd.CommandText = "select M_Photo from MemberPhoto where M_id='" + mSearch.Text + '";
DataSet ds = new DataSet();                    
OleDbDataAdapter da = new OleDbDataAdapter();
da.SelectCommand = cm;
da.Fill(ds, "MemberPhoto");

This may not be correct since I am judging simply on the syntax colouring applied by the Code Project <pre></pre> tags, which incidentally I have had to apply on your behalf).

This part appears not to be correctly formatted (everything after mSearch.Text + is considered to be one string.

cmd.CommandText = "select M_Photo from MemberPhoto where M_id='" + mSearch.Text + '";
DataSet ds = new DataSet();                    
OleDbDataAdapter da = new OleDbDataAdapter();
da.SelectCommand = cm;
da.Fill(ds, "MemberPhoto");                 
pictureBox1.Image = GetPhoto((byte[])dd.Tables[0].Rows[0]["M_Photo"]);

whereas

cmd.CommandText = "select M_Photo from MemberPhoto where M_id='" + mSearch.Text + "'"; 
DataSet ds = new DataSet();                    
OleDbDataAdapter da = new OleDbDataAdapter();
da.SelectCommand = cm;
da.Fill(ds, "MemberPhoto");                 
pictureBox1.Image = GetPhoto((byte[])dd.Tables[0].Rows[0]["M_Photo"]);

appears correctly formatted.

All of this could have been avoided by your using a 'parameterized query' (just Google that for examples). Doing so will also help to avoid SQLInjection attacks.
