script-generated images and internet explorer

[Bruno Carneiro da Cunha]

Hi all,

I wrote a small script that is supposed to get an image from a database and
return it to the user. The relevant part looks like this:

<?php
[...]
header('Content-type: image/jpeg');
header('Content-Disposition: inline; filename=".$image_name".);

print $image;
?>

This works fine in mozilla (and I guess netscape as well), but IE displays
the image as bitmap, regardless which instructions I send out to it. It
actually seems to decompress the jpeg back to bitmap before displaying,
because even if I try to save the file as jpeg it writes it in bitmap. I
though that these headers were pretty standard, and I am really puzzled as
to why IE doesn't take them into consideration.

Is there any way around this problem? T.I.A.

B.

I guess it's a completely different problem. Delete Temporary Internet
Files and try again.

IE is very funny about things like this. It seems to selectively ignore
mime types in favour of file extensions.

Try linking to your image script as follows:
<img src="yourscript.php/image.jpg">
which sometimes helps to confuse IE into doing things properly.

Indeed IE is broken. For anyone masochistic enough to wade through
it, Wacky Will's even written up its misbehaviour. The de rigueur
microfonts and technobabble come as standard, of course.
