That's exactly as expected. You've loaded your image into the FPGA configuration RAM. It will only be held while the power is on. Since your board powers up with a default configuration, it must have some flash memory installed to configure from. What you need to do is burn your configuration into the flash. Check what configuration method the board uses and use the Altera tools to create a programming file (not the same as the configuration file). Then use the programmer to burn the programming file onto your flash.
