Fix 2 errors for aspx site

My site here: [login to view URL] has an admin section that needs two errors fixed. 1. It is using CKeditor in the backend, the image uploader is not working. It was working before I changed server, so this is probably just a broken path. The error on upload is: Server Error in '/' Application. A generic error occurred in GDI+. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: [login to view URL]: A generic error occurred in GDI+.

I need to increase the amount of time that a user stays logged in. Currently if a user does not change pages for a while they are logged out. This causes problems when an administrator is editing a page. Sometimes they will spend a long time editing the page, then when they hit submit all the changes are lost. Please let me know if there are any questions about the project. Thanks
