By default SimpleMind Touch uploads Mind Map files to the SimpleMind server. Alternatively SimpleMind Touch can upload to a server of choice. The SimpleMind Touch application settings allow you to enter an alternative server URL. If you define a non-default upload server, this server should be able to accept POSTs for .pdf, .png and .smm files. The server response should be xml format describing the stored actual file URLs. If you are comfortable with .php and setting up a server to do this, please contact us by email for more details.
