i have a script to download an image once an hour to put it on my desktop.
i'm using httrack for that but it feels like catching flies with cannonballs...

it seems wget or curl would be the best choice but it does not work.

this one works:
httrack -T30 -R10 --get http://static.die.net/earth/mollweide/1024.jpg
and all of those don't:
wget --output-document=1024.jpg "http://static.die.net/earth/mollweide/1024.jpg"
curl -o 1024.jpg http://static.die.net/earth/mollweide/1024.jpg
wget http://static.die.net/earth/mollweide/1024.jpg
- everytime it downloads only 37 bytes, saying it's image/gif.

it's not a big problem but i'd like to solve it.

any help? thanks.
