hi, i am using a ibook g4 which has added ram and is updated with leopard. however i am battling the "start up disk is almost full" problem too. now, i have uploaded pics from my camera to iphoto(which until recently has worked perfectly fine), looked at them, edited them, and now i can see the little version but then i double click the pic as if i was going to edit it and it does not come up. this is not true of all the pics, just random ones... i tryed to put them on a flash drive and transfer them to another mac and see if theyd come up then, but they dont. i dont understand where these files have gone, and why they arent showing up... and ive deleted them off my camera so are the just completely gone?? thanks for your help!!
