Ah that's intriguing, thank you for looking into this, waxdoc! It never occurred to me to try different OS's.
Yes, perhaps it is something to do with the actionscript. Since I didn't write the .XML or .SWF, it's just a auto-generated html/gallery page/object from Picasa in which I've basically redirected the links and placed it as an object, not as a link to a full-size page (as is default)- I thought it may have confused it.
I tried again on a different free host: www.ssmarine.happyhost.org/temerity_ii
and this seems to work fine, perhaps it is the sort of hosting system that has done this?
I guess it would be useful to find out what caused this, but at least I know now it's not universally wrong. Thanks again for analyzing the page!
