Thanks, gif displayed when remove 'start_html' lines. CGI manual says'The start_html() routine creates the top of the page, along with a lot of optional information that controls the page's appearance and behavior.This method returns a canned HTML header and the opening <body> tag. '. It seems to have nothing with displaying images, I am still confused why remove it can take effect.	[reply]

For the same reason that: `cat foo.html bar.gif baz.html > quux.gif` will create a file that is neither valid HTML nor a valid GIF. (Interestingly `cat bar.gif baz.html > quux.gif` does create a valid GIF.)	[reply] [d/l] [select]

Because calling it adds some lines to the output that do not belong to the image. The "image file" thus becomes corrupted and cannot be displayed (or even cannot be recognised as a picture).	[reply]
