newbie: image problems again

[Jeff]

hey

asp.net 2.0

my problem is that on a webpage am I trying to dynamically display the image
a user has uploaded. But the webpage doesn't display the image. The browser
displays the standard image telling that image not found / broken image link
etc....

This is the code which saves the image to hard drive...:
fullsizeImage.Save(Server.MapPath("~/Images/Fullsize/" + Profile.UserName +
".jpeg"));

This is my code for displaying the image, it's in Page_Load event of
webpage:
imgPicture.ImageUrl = Server.MapPath("~/Images/Fullsize/" + Profile.UserName
+ ".jpeg");

The image exist in that folder

Any suggestions to this error?

Hi Jeff,

does this variable "Profile.UserName" really exist when you try to load the
image. Did you place an exception-handler around the loading-method?

Bye,

Hey

it looks like Profile.UserName is empty...
But this code doesn't work either:
imgPicture.ImageUrl = Server.MapPath("~/Images/Fullsize/test.jpeg");

I've also tryed this (setting it directly in the source, not the code
behind):
src='<%# Eval("~/Images/Fullsize/test.jpeg") %>'
Without any success....

any suggestions?

Hi Jeff,

I am not sure what your problem is, but try one of these two things:
1. If you are using something like VS.Net, then simply try to locate a
test image using the properties grid of the Image Control. And then try
to run your page and see if it works.

2. try printing the path you are trying to assign to the ImageUrl
property by using a Response.Write() from the code behind.
So basically Response.Write(Server.MapPath("~\.....

I have a feeling you are doing a bit too much in trying to assign a
path to the ImageUrl property.

The path is
C:\Documents and Settings\Jeff\My Documents\Visual Studio
2005\WebSites\BN\Images\Fullsize\test.jpeg

I've checked and path is correct, but the path contains spaces....

I'm not sure about it but maybe the browser need to know if this is a
picture ("image/thumb")???

It is possible that you may need to grant permission to the asp.net
process on that image directory. It might be a problem with the
security.

I replaced this line:

imgPicture.ImageUrl = Server.MapPath("~/Images/Fullsize/test.jpeg");

with this line

imgPicture.ImageUrl = "~/Images/Fullsize/test.jpeg";

And now it works

Thank you very much for helping me with this. The best thing with this
problem is that I've learned from it -> maybe using Server.MapPath isn't
best all the times....

Best Regards!
