image.src

[Jeff]

Hey

asp.net 2.0

I have a webpage which generate thumbnail images. In another webpage I want
to display these images...
I tryed using this solution:
<img ID="photo" src="../../images/helloworld.jpeg"/>
But this gives this error:
File '../../images/helloworld.jpeg' was not found

The file helloworld.jpeg exist in the ../../images/ folder.....

If I in solution explorer right click and choose "Add Existing Item" and add
this image, then this works.... but the images are generated dynamically in
runtime so adding them to the project isn't a good solution

Any ideas what I should do to solve this?

If the images are generated dynamically in runtime, why are you
refering to them statically at compile time?

I suggest either:
1) adding a "dummy" image that is replaced at runtime with the real image
or
2) removing the static reference and setting the src property at runtime

Hmm the code I mentioned above was just an example, I've also tryed this
way:
<img ID="photo" src= "<%# Eval("File") %>"/> but it gives the same error....

I wonder about your 2. suggestion:
This list of images are displayed in a Repeater control. Is it a good
solution to use the rptInbox_ItemDataBound (my repeaer control's ID =
rptInbox) event do dynamically add the image to the webpage or are there
some other event's which suits better?... Sorry if my questions sounds odd,
but I'm a newbie...

I take it the *browser* gives that errormessage?
What is in the html that the browser received (do a "view source").
Does the "src" still point to the directory you think it should point
at?
Reason: if the "src" attribute is processed by the asp.net environment
(as it will be when you add a runat=server attribute), then it might be
changed. When this code is in an ascx, the path is taken to be relative
to the *ascx*, not relative to the aspx it ends up in.
When this is the case, you could use "webapp-root-relative" paths, by
starting with a "~" (~/images/helloworld.jpeg). This will work wherever
the application is installed: //localhost/theApp/Web or
//www.somesite.com

This should work, but you should fix the outer quotes into single quotes:

We all were newbies once... so that's no problem.
ItemDataBound is ok, but the Eval method above is the preferred one.
