PS: I tried several locations in the exif_read_data array, because i've found online that the Orientation header can be present in several places. I think the EXIF Orientation head will be lost in thumbnails, but i don't think that's a problem, since they will be in the correct size and orientation now. With this fix, original images are kept untouched, and thumbnails are generated correctly. I implemented it in production for my site using a separate class that extends the load method of WP_Image_Editor_GD. I just posted a patch for this, that fixed it in my case. In addition to EXIF, it also contains IPTC and ICC Profile metadata, to test that part of my patch.Įmbedded-thumbnails-windows-explorer.png ( 40.8 KB) - added by pbiron 3 years ago.Įxample of Windows Exploring using the unrotated embedded thumbnail for an image that has be rotated on uploadġ4459.4.diff ( 8.5 KB) - added by azaozz 3 years ago.ġ4459.5.diff ( 9.3 KB) - added by azaozz 3 years ago.
