Still don't know how to make the images load into it. To get it to boot is pretty simple, put a flipbook.h file in your include/startup directory with these contents -
gui.externalFlipbookPath = "/mnt/apps/fc_mp_pro_300_rc3/bin/framecycler";
gui.flipbookStdInArg = "";
gui.flipbookExtraArgs = "";
gui.flipbookZoomArg = "";
gui.flipbookTimeArg = "";
gui.flipbookFPSArg = "";
Obviously the path to framecyler is probably different for you. This straight from the manual.
Any one got the answer to getting images in??
