Sorry cant help u much... the code looks fine. However my guess is that your module is not getting loaded for some reason. Why dont u debug the code and see if ur onHeaderModuleReady function is getting called or not. The most likely expanation is that it isnt and because of that ur variable jpl_head never gets initialized. Another thing that u can see before debugging is when the application loads is the default image (jpl_head.png) getting displayed on the screen. If it is then there is something else wrong in the code and u wont find out without debugging.
Sorry if I am stating the obvious.
