Can someone please help me with the following: I need to show a default image in the event that a dynamic image does not exist. I am using asp/vb dreamweaver.
The dynamic url to the image in dreamweaver is:
<img src="localhost/universal/photos/<%=(Recordset1.Fields.Item("MLS_NUMBER".Value)%>.1.jpg">
This works fine when an image exists.
But when an image does not exist, I want the page to show a default image which resides in my local images folder:
images/noimage.jpg
Now I began to write some ASP to do this but it doesnt work.
Can someone tell me what I am doing wrong?
<%
myPic="" & (Recordset1.Fields.Item("MLS_NUMBER".Value)
If Len(myPic) = 0 Then
myPic ="noimage.jpg"
Else
myPic=myPic & "1.jpg"
End If
%>
<img src="localhost/universal/photos/<%=myPic%>">
Thanks
Steve

Hi Steve
Does the db send back a NULL value if no image name is stored in the field or an empty string, these are classed as different things and need to be checked for differently?
<%
Dim myPic
If IsNull(Recordset1.Fields.Item("MLS_NUMBER".Value) = True Then
myPic = 1.jpg
ElseIf (Recordset1.Fields.Item("MLS_NUMBER".Value) = "" Then
myPic = 1.jpg
Else
myPic = (Recordset1.Fields.Item("MLS_NUMBER".Value)
End If
%>
<img src="localhost/universal/photos/<%=myPic%>">
