Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Description:
------------
while running as cgi on nginx(the response is 'chunked' according to
firebug), and ob_start is activated using imagepng,imagegif to
outputimages to the browsers, these two are not correct, the browser
only received part of the image, while imagejpeg is correct. And without
ob_start or running as apache+mod_php(response not 'chunked') all three
are correct. And if add
'ob_end_clean()' before imagepng, it worked correctly.
