Brion, thanks for replying.
As it turned out that it was a simple matter of running out of disk space.
I had initially guessed that was the case, from looking at the half-built thumbnail, but when the host admin told me that he had increased the quota and it didn't help then I went off looking for other reasons, didn't find any, and ended up posting to the list.
It seems that despite the quota being increased, there was a quota lock in place that stayed until you deleted something. When I went in via SSH to make a backup of LocalSettings.php it failed with a obvious quota error, I deleted some old crap and bada-bing ! it all worked again ! :-) - (sighs of relief all-around at discovering it was a *simple* problem)
thanks everyone for your suggestions, and hopefully the archive of this thread will help someone else in future.
cheers, darren. ps - all the pubcrawl photos that took over the quota limit / disk space are up now :-) http://law.flindersclubs.asn.au/wiki/index.php?title=Main_Page

If your hosting company won't talk to you, you need to find a hosting company that's responsive to their customers' needs.
More generally, you should have at this point already checked the session configuration and whether you need to for instance use a configuration such as that recommended for http://meta.wikimedia.org/wiki/Running_MediaWiki_on_Sourceforge.net
If this is a public-facing wiki, you should upgrade to 1.4.12 regardless of whether it has anything to do with this problem, as there are security and data corruption issues resolved by newer releases.
