I reckon that means you're using the placemark from the top post in this thread, which points to http://xplanet.dyndns.org/clouds/clouds_2048.jpg

Looking at http://xplanet.dyndns.org/clouds in my browser, it appears that the images there are either broken or not being updated

But if you scroll down to the post marked 'Now with Transparency' there is a second placemark... and that appears to point to the author's own website.

I'm getting a picture with that placemark, but I have no idea whether it is 'fresh' or an old one.

Perhaps the two placemark makers can update us on the situation?...

{EDIT: I have looked through the thread, and it appears that the 'Now With Transparency' placemark is updaing from a different source, namely: http://userpage.fu-berlin.de/~jml/clouds_2048.jpg - which appears to be displaying a valid image today, at least!

So, my advice, JollyReaper, is to use the second placemark, instead of the top one. Use the one with transparencey, from ChrisMDP}
