Hi all,
I'm trying to make a demonstration script (using PHP) that demonstrates the
use of MIME types in HTTP headers. It should send the Content-Type header
and than sends an image to the browser in hex.
I run the script in my browser and get the bare decimal values displayed and
not the GIF image:
Content-type: image/gif
7173705655977010247000001280001280128128000128128012801281281921921921922201
92166202240643209632012832016032019
--snip--
I also tried to use:
header("Content-type: image/gif");
But no success.
I don't want to use the header() function cause it doesn't help my
demostration script show the workings.
Where does it go wrong? (See script below)
Regards;
Eelco.
