哪个大侠帮我解决这个问题,我高分相送!

问题是这样的,我现在做的是一个人事管理系统,我的要求是要把照片存放到SQL中,我已经在SQL的表中设了一个字段为image的列的，列名为picture．
现在就是我在查看每位员工的时候，我要求他的照片也就显示在我在前台ＶＢ里设的image控件中了．
我的前台语言是ＶＢ．
这个问题我已经搞了好久了，没有一个答案．
我本来的做法是把图片放在Ｄ盘的一个叫pic的文件夹下，照片的命名是以每个员工的工号来命名的，因为工号唯一．所以每次跳出来的照片也不会有错误的，可是主管的意思是要我把照片存在ＳＱＬ中，这个我就不知道怎么实现了
看了以前的一个关于image的贴子，我也是一头雾水，不明白
所以恳请大家帮忙，今天是最后的期限了，要不然我就不好交差了．
可可我先在这感谢大家了！！

给一个vb的例子给你
Dim cn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim stm As ADODB.Stream

Private Sub SavePictureToDB(cn As ADODB.Connection)
'将BMP图片存入数据库
On Error GoTo EH
    Set stm = New ADODB.Stream
    rs.Open "select ImagePath,ImageValue from tbl_Image", cn, adOpenKeyset, adLockOptimistic
    CommonDialog1.ShowOpen
    Text1.Text = CommonDialog1.FileName

    With stm
         .Type = adTypeBinary
         .Open
         .LoadFromFile CommonDialog1.FileName

         .Fields("ImageValue") = stm.Read
         .Update
    End With
    rs.Close

为什么不存放图片的路径

我喜欢只在数据库里面放路径

唉，
很麻烦呀！
虽然问题还是没有解决，
但是看在大家都这么热心的份上，
给分了！
我现在是用的存储路径的办法来做的，能用就好了！
