Hi,
I'm ready with my plugin and want to share it with you. I'm not a
python programmer, so it might not be well written (exception handling
for example). It's a plugin that grabs Dilbert strips from the web and
stores them in a directory. Three menu items appears in image section
if it is activated.
Place these lines in local_conf.py:
DILBERT_DIR='/home/freevo/media/images/dilbert/'
plugin.activate('image.dilbert')
