Need to Retrieve an Image File on Another LAN Server

[=?Utf-8?B?SmVmZlAtPg==?=]

I want to retrieve an image file (TIF) convert it to a bmp file and enable
sizing.

I know how to do the converting & sizing part, and store any atributes to
file location in the webconfig, what I don't know is how to get the image
file.

The only way that I've got it working was to Impersonate a user login at the
other server.

Potential clues...
Image.FromFile
Server.MapPath
URL

Any links or similar are appreciated.

You should always know "who" is running the code.

LocalMachine\AS PNET account is typical.
Thus this account would need permissions to read the files on the file
server.

OR you can do impersonation as you see.

Here is some crappy code to ID the account running........ ....
Don't assume, check it when you don't know.
private string FindIIdentity()

{

try

{

//'Dim user As WindowsPrincipa l =
CType(System.Th reading.Thread. CurrentPrincipa l, WindowsPrincipa l)

//'Dim ident As IIdentity = user.Identity

string returnValue = string.Empty;

WindowsIdentity ident = WindowsIdentity .GetCurrent();

returnValue = ident.Name;

try

{

returnValue += " on " + System.Environm ent.MachineName ;

}

catch (Exception ex)

{

Console.WriteLi ne(ex.Message);

}

return returnValue;

}

catch (Exception ex)

{

Conditionals.Tr ace.WriteMessag e(ex.Message);

return "Error Finding Identity";

}

}

Here is the code i am using (from ASP.NET) to access shared folder. You
obviously must have User/Password to access that folder.
