hi again! Thanks for all the replies. I have left the camera unattended now for 5 weeks(connected to a power supply), and there have been some minor problems. After about 3 weeks running, the camera suddenly started to take a whole bunch of pictures! It shot pictures nonstop until the memory card was full (around 7500 shots) and then shut down. I am currently studying in another part of the country so I have not been able to check the status too often. After all i suspect the camera will shut down when a certain temperature is being read from the sensors? It seems leaving the camera connected to a power supply for a whole year would not been a smart thing to do, so I will have to abandon this project:( BTW the camera still works fine though:) I did not have time to test the daily shot script so i have used the interval no stop script. It did not work as I mentioned above.
