You could have wget (or something similar like LWP (libwww-perl)) download the image periodically via a cron job, and save it to wherever KDE expects to find it. (Or even use some KDE built-in polling mechanism to periodically fetch the file -- not sure whether there is such a thing... I'm not using KDE). In any case, you'd first have to find out what the exact image URL is. For this, just navigate to the desired page using your browser, and cut-n-paste the direct URL to the JPG/GIF/TIFF into your wget script... If you're lucky, the image URL will not change, although the image behind it is being updated -- so you just need to fetch a static URL. In case URLs should change, or if some form of non-trivial authentication is required, then LWP might be better suited than wget, as Perl makes it easy to do any scripting required... (Actually, I've done something like this some time ago, but then decided that I - in the long run - still like my self-shot sceneries much more than various arrangements of clouds on my desktop :) -- in particular, as I wasn't able to find any server that _reliably_ delivers reasonably hi-res, up-to-date satellite or radar images...)
