Image Uploader Error

[ninja.ms]

I need some help with this image uploader. I am getting an error each time that I try to upload an image through the CMS.
The error that I am receiving is:

C:\InetOxford\images\page\ClientProfileChart.gifThread was being aborted.Upload Failed

I am fairly knew to .net sites and don't know much about image uplaoders that use .aspx

Any help would be great! Thanks!

Hello,

You should give write security permission to the Windows account which runs the .NET application (add the user in the upload folder security properties ang give write/modify permissions). In Windows XP - the ASP.NET machine account, in Windows Server - the Network Machine account.

so i had the client's IT guy do this and it still does not work. I'm still getting the error message of this: D:\inetpub\wwwroot\Test\Test-Oxford.Mediasauce.Com\images\page\ClientProfileChart.gifThread was being aborted.Upload Failed

any other suggestions?

thanks!

Where are you seeing this error message? You should get a call stack and exception with the error message. That is what will help solve this problem.
