Weather URL Problem

[Minus]

I try to add some weather URL but any of these are correctly display.

For example, this url about Night and Day on Earth with GPS position wich generated a JPG pic :
http://www.fourmilab.ch/cgi-bin/Earth?i ... le=&date=0

During my debug, everything seems to be ok,
the tmp file is correctly generated but nothing is display in DomotiGa.

Is there any spec to add a pic like size, format or something else ?

It only seem to display (animated) and normal gifs for now.. I have added support for other images formats, will test and upload it.
