Displaying images with CGI

[DaveGill]

Hi,
I'm quite new to CGI programming but what I want to do is display an image using a CGI application. I've written an app that reads a TIF file, converts it to PNG then writes it to stdout. If I redirect the output to a file I can then view the file but if I try and display it in a html pages ising <img src=&quot;test.cgi&quot;> nothing is displayed. Is there something I'm missing?

Thanks
David

Are you printing the appropriate content-type header first?
Something like this:

print "Content-type: image/png\n\n";

I've tried that but it still doesn't work.

Are you writing the output in binmode? Image format files need to be processed as binaries to avoid the end-of-line termination string being added by the web server.
