CalHob Code grabs comic strip from webpage. I live in Australia so it actually grabs the image from yesterday.
YESTERDAY=`TZ=aaa24 date +%y%m%d`
It was just easier for me that way due to time zone differences. You will need to change USERNAME to your username in the file paths:
if [ $DAY == "Sun" ]
then
FILE="file://localhost/Users/USERNAME/Pictures/latestCalHob.jpg"
else
FILE="file://localhost/Users/USERNAME/Pictures/latestCalHob.gif"
fi
To display the file, create an image geeklet and name it "CalHob Pic". Make sure it's big enough to display the larger Sunday comic.
