Thanks! I tried changing the value to 500 as well as replacing the three lines, to no avail. Still no photos. I'll check out the other script you mentioned.
Hmmm .. if that didn't work then there is something else wrong.
Let's try something simple. There are a few really short test scripts included in the A/CHDK/SCRIPTS folder on your SD card. Try the one called
shoot.lua . Load it and run by pressing the shutter button. Does it create a new image?
when I go to retrieve the files, I get an error that there are no images.
In case I'm missing something obvious here - what error do you get? Exactly what are you doing to retrieve the images? Are you just switching to Play mode to review? If so, can you create an image without CHDK loaded (just normal picture taking mode)? Can you see it?
