Try changing your editor to "None" and making sure that there is no source code left in the input box. If there is no source code and/or the module is not published it won't appear on the front end. If it does clear your cache and check everything that is published here. Also keep in mind the following restrictions regarding this position:
This is the custom_1 position, it is designed only for the image slide module. This position does not appear on IE7/8, in its place custom_3 will show, and only shows for IE7/8.
