yep, you can define a custom script in the config
please take a look at /usr/share/cairo-dock/plug-ins/dnd2share/upload2free.sh, it's used to upload files to free.fr
$1 is the file, $2 is the optional rate limit, and the script should simply write the URL on the output
I saw that file earlier, but it seems a little daunting not knowing what i am doing. I can have a go at hacking it and see how I get on with it. I was just kind of hoping that someone else would already have a custom script for use with flickr as flickr has given 1TB of space to it's users now...
