I would not say it is a corupt file name, I would think it is because the file
names for the two pictures in question contain characters which are from a
foreign language. http://www.peterkarby.com/gallery/thumbnails/havel?ge1_.jpg
& http://www.peterkarby.com/gallery/pages/Bj?rnBorg2.jpg . On my IE6 the
latter is fine for the thumbnail because it does not have the character in the
filename that IE6 does not understand (on my computer). The enlarged linked
page does not work because it has the character in it. The former one does not
work for me as either the thumb or the linked page because they both have that
character. I suspect that if I downloaded the IE6 support for that language
the page would be ok. If I were you I would stick to common english characters
for file names.
