I can confirm the reported behavior, but I cannot see why that would be a bug. The PHP warning for the unmodified image correlates to exiftool's: Warning : Bad MakerNotes directory Previous Comments: ------------------------------------------------------------------------ [2020-06-11 12:53:23] cmb@php.net Could you please make the image file available somewhere else for download? ------------------------------------------------------------------------ [2020-06-11 09:39:24] 7tonin at laposte dot net exif_read_data function is also impacted ------------------------------------------------------------------------ [2020-06-11 09:34:05] 7tonin at laposte dot net Description: ------------ The thumbnail of a SONY picture can not be loaded with exif_thumbnail function. PHP Warning: exif_thumbnail(image.jpg): IFD data too short: 0x000C offset 0x000C IFD0.Make : SONY IFD0.Model : DSC-W55 EXIF.MakerNote (not seen) : SONY DSC But, by changing the Exif:make tag value from SONY to Sony, or to SYNO, or even almost whatever else, the thumbnail is loaded. Switching from "SONY" to "Sony" value for Exif:make tag changes the way PHP see the Exif sections. This topic from exiftool.org forum gives details about struggle around this problem. https://exiftool.org/forum/index.php?topic=11303.0 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79687&edit=1
