records deleted from database when uploading files - database

Question

When i try to upload multiple pictures to the database my code works fine and all the pictures show in the gallery, but when i try to modify the picture in the database, and modify one picture it deletes the rest of the pictures from the database. The recordset isnt deleted and the rest of the information stays the same, its just the 5+ places i have for the pictures whose data gets deleted. here is my code so far..
message.Text = "please wait"
pics.Visible = False
'wherepics are stored
Dim savepath As String = Server.MapPath("/cgi-bin/properties/")
Dim tfn0 As String = ""
Dim tfn1 As String = ""
'dims the filenames a variables
Dim img0 As String = pic0.FileName
Dim img1 As String = pic1.FileName
'this is the set of paths to check
'this will check for redundencies in the database so no dublicate file names will occur
Dim ptc0 As String = savepath + img0
Dim ptc1 As String = savepath + img1
Dim url0 As String = ""
Dim url1 As String = ""
Dim counter As Integer = 2
If (System.IO.File.Exists(ptc0)) Then
While (System.IO.File.Exists(ptc0))
tfn0 = counter.ToString = img0
ptc0 = savepath + tfn0
counter = counter + 1
End While
ElseIf (System.IO.File.Exists(ptc1)) Then
While (System.IO.File.Exists(ptc1))
tfn1 = counter.ToString = img1
ptc1 = savepath + tfn1
counter = counter + 1
End While
End If
Dim sp0 As String = savepath + img0
Dim sp1 As String = savepath + img1
If Not pic0.FileName = Nothing Then
pic0.SaveAs(sp0)
img0 = pic0.FileName
url0 += "pic_main"
url1 += img0
End If
If Not pic1.FileName = Nothing Then
If pic0.FileName = Nothing Then
pic1.SaveAs(sp1)
img1 = pic0.FileName
url0 += "pic_one"
url1 += img1
Else
pic1.SaveAs(sp1)
img1 = pic0.FileName
url0 += ", pic_one"
url1 += ", " & img1
End If
End If
Dim datanames() As String = {url0}
', "pic_six", "pic_seven", "pic_eight", "pic_nine"
Dim datavalues() As String = {url1}
', file6, file7, file8, file9
DB.UpdateCommand(datanames, datavalues, "property", "property_id = " & Request.QueryString("id")) ', true)
Response.Redirect("finished.aspx")

I have found the solution it was looking at all of the file upload controls, since nothing was in them it would reference those fields I had this figured out a while ago, got busy and never found time to post my answer. in the database and delete anything that was in it and replace it with a blank space. I changed the code a bit to where the users chooses the slot in which they want to update, then carry over a qstring instead of having it update all of them at once
