Re: Problem viewing uploaded images using ASP.NET

Hello Kevin,

When you see the script in the first thread. And I explain to you that
when I use that script to upload image files to a virtual folder that
has write permission assigned. When I do that using a webbrowser (so I
browse to the URL where the above ASP.NET script has been made
available) I am able to upload the image file and is saved in
correctly. No problem so far, the script it doing what it should do.

But, when I than try to open the uploaded image file using a
webbrowser, I am
prompted for a Windows logon screen in my webbrowser.

Trying to solve my problem I uploaded a test image using FTP to the
same folder as where the image file is located that I just uploaded
using the ASP.NET script. When I try to open that image file using a
webbrowser I am NOT prompted for a Windows logon box.

So, I think to conclude that the ASP.NET script has the right to save
the image files to the folder. (the file is saved in the folder) But I
think for some reason it is saving it with a different permissions
assigned as when I upload it using FTP.

What I tried to explain with the webbased administration tool from the
provider is that I can not see what actual permissions are assigned to
the (uploaded) files and the folder. I only have the option to select a
file or folder and select: "WRITE", "READ", "RESTORE DEFAULT
PERMISSION".

For me it seems not have to do with the ASP.NET account because than I
would been unable to save the file in the folder. I must be some
default permission that is missing when saving a file using the ASP.NET
script.

Is there a function available in ASP.NET so I can list this permission
assigned to the image files and folder or even change it?

Thanks.
