In the past I have downloaded Tiff files of census images from
<http://www.census.pro.gov.uk> and found that they opened OK with Quicktime
Pictureviewer. That said, with other images I often find that some
corruption when downloading will leave them not openable in Quicktime but
most time Graphic Converter will open them.

I always prefer to download files like this to the desktop and then open
them directly rather than use the browser with "file helpers" Once you have
the file you can try any variety of image viewer you have (or find others
via, say, Version tracker) although I'd be very surprised if Graphic
Converter couldn't open any kind of Tiff.

Again this sounds like you are trying to open them with the browser & a
"file helper". Are you able to just download the file to the desktop (or
other appropriate download folder). With either Safari or Internet Explorer
just right-click (or control-click) on the link to the TIFF file and choose
the "download link to disk" option.

Sometimes, if the link is not directly to the file but initiates some
trickery to generate the file, the "download link to disk" option may not be
available - in this case I have had some success by temporarily changing the
browser preferences to download directly rather than use a helper. Eg, on my
version of explorer under "Download Options" set the "Download Destination"
to "Always download files to the download folder" rather than "Always use
download location from appropriate file helpers" . I don't use safari much
but on my version of Safari, I would try unticking the "Open safe files
after downloading" box.

As discussed above, I would definitely try and separate the downloading from
the file opening. If you can actually download the file to the computer then
you should be able to find some way to open it.

If the file downloads OK but the problem is just a Mac viewer I'd be
surprised cos AFAIK that would mean a non standard TIFF file and they are
trying to tell you they are using an industry standard. However you would at
least have the file and if the only thing that will open it is a windows
viewer you may have the option of opening it on a PC and saving it in a more
"standard" "standard format"!

I suspect the problem may lie with the the fact that you are trying to open
it through the browser with a helper application. So try and keep the helper
application out of the loop.

Of course, the above is all very general and may not address the problem at
all - but it should be pretty easy to give it a try!

Hope that helps

Cheers

Neil
