Here you say it's impossible to save, but then further down you contradict
this by saying that you did manage to save it - only the transparency
disappears.
Please try to describe your problem accurately so that you don't confuse the
people who may want to help!

OK try this:
1) stream the image, then in your browser save the image to file.
2) don't stream the image, instead save it as file on the server, then ftp (or
whatever) the file back to your local computer.
3) now compare the two files to see if they are the same. In Windows use the
file compare program 'fc', in *nix use 'diff'. Remember to do a binary
comparison in both cases.
If both files are exactly the same then you've got a crappy browser - it
should display an image file in the same manner regardless of what headers
came with it.
