I just noticed on one of my sites that my php script that calls header(“Content-type: image/png”) and imagepng(), etc., is not creating a png image. This was working before but I’ve not only switched to nginx from Apache, I’ve also switched to a new server, new build of PHP, etc… Do I need to do something special with the nginx config to make this happen? ---

Your problem is almost certainly related to directory permissions or a missing PHP library. Cliff ---

no, that’d be a php thing most likely. try firefox it’s a bit more forgiving with incorrect headers. it could be the build of php doesn’t support it, or you have extra characters in the file being outputted before the png data, so the browser is getting trash… that’s usually the case i see.

thx for the ideas and you’re right, not an nginx issue. Not sure what was exactly the final step but I did need to clean up some of php’s config options. ---
