You can choose to use the shortcuts in this post in your scripts (I have), for simplicity reasons, I am not including them in what I post here.
First thing you will have to do is go to weather.com and find the name of your map for your local. The url or the images should be something like this:
image.weather.com/looper/archive/(name of your map)/1L.jpg?1213024402403
I will leave Kentucky in the scripts for easy reference.
The first script is the one to pull the images:
#Cd to directory so wget will download files there
#Get images for weather
while [ 1 ]; do
wget -N http://image.weather.com/looper/archive/us_lex_closeradar_plus_usen/1L.jpg?1213024402403
wget -N http://image.weather.com/looper/archive/us_lex_closeradar_plus_usen/2L.jpg?1213024402403
wget -N http://image.weather.com/looper/archive/us_lex_closeradar_plus_usen/3L.jpg?1213024402403
wget -N http://image.weather.com/looper/archive/us_lex_closeradar_plus_usen/4L.jpg?1213024402403
wget -N http://image.weather.com/looper/archive/us_lex_closeradar_plus_usen/5L.jpg?1213024402403
#Resize the images
mogrify -resize 311x210 /home/(user)/(folder)/*.*
Edit as needed.
Second script is to launch feh and run the slideshow:
feh -g 311x210 -D .4 -x -s /home/(user)/(folder)/
And to make it all run (in Openbox at least autostart.sh):
/home/(user)/(script location)/myweather.sh &
/home/(user)/(script location)/feh.sh &
You can play with the sizes if need be, they work fine on my 32 inch monitor.
When feh starts it will more then like be up at the top left, hold alt+click to drag where wanted (needed everytime started, minor annoyance)
Make sure when you paste these into whatever that the wgets are on one line per.
Hope you enjoy!
