Replace Image If Not Uploaded

Posted on 2004-08-31

I have been trying to find out ever where and can not find the answer, I have asked the same or similar question before but cant get a complete answer. When people add information to the website they have the option of uploading an image, if they don't upload an image we are stuck with that little x box.

I want to have it so if no image is uploaded that there is text saying "No Image Available" or "No Picture"

This is a ASP.NET Dreamweaver MX question, hosting on Windows 2003 server, database MsSQL

This is the code that I have on the page right now:

<img src="<%# Thumbnail("Prefix","small_", dsProperty.FieldValue("Image_01", Container) ) %>" name="Image_01" id="Image_01"/>

This is what I think it might be, but it does not work:

<if isEmpty(dsProperty(Image_01)) Response.Write "No Image Available" else Response.Write "<img src="<%# Thumbnail("Prefix","small_", dsProperty.FieldValue("Image_01", Container) ) %>" name="Image_01" id="Image_01"/>

I have been trying to get this figured out for a long time with out any luck.

isEmpty means the Variable Provided as Parameter in it has no Value Assigned to it.
Now in your Database how is the Value s Stored when no image is provided?

I assume You are storing Image names in Database.

if no Image is Provided and Column Defaults to a Null Value Then Try

if isNull(Img_Filed_Name)

OR try this

if Len(Img_Field) <= 0


if Img_Filed = ""

You can also Put all of them together

if isNull(Field) OR Field = ""  OR Len(fld)  = ""

Again it depends how is your Databse Structured. if none of the above helped Then Post how you storing images in Databse.

Macromedia, sent me this as a alternative, but it will not work, below is the error.

dim imgName = dsProperty.FieldValue("Image_01, Container")
If isEmpty(imgName) Then
  Response.Write "No Image"
  Response.Write "<img src= + <%# Thumbnail("Prefix","small_", dsProperty.FieldValue("Image_01", Container) ) %>>" Endif %>

> If isEmpty(imgName) Then

Make Sure imgName is a Variable name, and has some value Set to it.
