SSRS 2005 does not support PUT requests for image uploads. The HTTP 405 error message you received indicates that the PUT method is not allowed for the URL. According to the Microsoft documentation, the HTTP PUT method is not supported in SSRS 2005. However, you can upload images to the SSRS server using other methods such as the HTTP POST method. You can also upload images to the server by using the Report Manager or the Report Server Web service. For more information on supported HTTP methods in SSRS, please refer to the Microsoft documentation.
