I keep having this error message pop up... I also added Write permissions as explained in the error message...

Anything else I needed to make this work?

EXCEPTION
The control was unable to generate an image on the server.
CAUSE
The server control needs a special folder where to store the generated images.This error can occur if the folder does not exist or if the control does not have the necessary permissions to write to it.
RESOLUTION
Manually create the directory and assign read, write and browse folder contents permissions to it for the ASPNET account. Task list:
1) Create the folder [C:\WebSites\20120815_002\NevronTemp]
2) Right Click on the folder and select Properties
3) Select the Security tab
4) Click Add, select the ASPNET user account and then click OK
5) Check the Write, Read, List folder contents and Read and Execute checkboxes
6) Apply settings and press OK

Hi Conrad,

Try to check if this is indeed a security problem by temporary granting "Everyone" access to the specified folder (make sure to turn off LAN when you do so). Also check what happens when you assign ASP.NET and System accounts full trust to that folder. You can also workaround the problem by using direct image streaming to browser which does not require hard drive access. Let us know if the problem persists.

yes, rights granted to "Everyone" ann addittion to ASPNET, SYSTEM and Administrator users... nothing seems to work... this is on Windows 2000 Server...

How can I implement streaming without writing to the harddrive?

Hi Conrad,

Check out the Getting Started\Binary Streaming image example - if shows how to render images directly without storing them on the server. You can also use HttpHandlers, which is the default mode for recent versions, however we're not sure if the version you currently use supports it. Let us know if you meet any problems.
