As I understand it, that is the default in libgd, see <https://github.com/libgd/libgd/blob/gd-2.2.1/src/gd_jpeg.c#L413-L416>. ------------------------------------------------------------------------ [2016-06-15 09:13:02] opajaap at opajaap dot nl Thank you. ini_set( 'gd.jpeg_ignore_warning', true ); is an acceptable workaround. Orientation is not a problem, I can handle exif and orientations. ------------------------------------------------------------------------ [2016-06-15 00:02:46] cmb@php.net Setting gd.jpeg_ignore_warning=1 in php.ini solved the problem that the JPEG couldn't be read. Please verify this[1]. If that works, you'll find that the image is bottom up when read by GD. That is because the image data are stored that way, and the Exif Orientation flag is supposed to signal a reader that the image has to rotated by 180° (its value is 3[2][3]). However, GD is not supposed to regard Exif data, so you'd have to rotate the image yourself if necessary.

Calling imagecreatefromjpeg() on this image gives me an additional warning: > imagecreatefromjpeg(): gd-jpeg, libjpeg: recoverable error: > Invalid SOS parameters for sequential JPEG Have to investigate further. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
