 * The warning message could be caused by one of three things:
 * 1) Corrupted/unsupported EXIF data in the `Power-Firm-QMS.jpg` file
    2) Malicious
   EXIF data in the `Power-Firm-QMS.jpg` file 3) A bug in the PHP EXIF extension(
   could be related to both of the above)
 * Since this is a one-time occurrence, there is no way to determine which of the
   above three is the cause. I suggest using an external application to strip the
   EXIF data from the image, then updating the image on your WP site with the cleansed
   version.
 * You should also document the text of the warning, and the source of the image,
   in the event you encounter an `exif_read_data()` warning in the future. This 
   information may help you determine the cause of the new warning message.

 * Here is the related trac ticket. [https://core.trac.wordpress.org/ticket/42480](https://core.trac.wordpress.org/ticket/42480)
 * The warning is only shown if the debug mode is enabled [https://github.com/WordPress/WordPress/blob/5.8-branch/wp-admin/includes/image.php#L805](https://github.com/WordPress/WordPress/blob/5.8-branch/wp-admin/includes/image.php#L805)
 * I am not sure what you can do in Photoshop to fix this.

 * [@grapplerulrich](https://wordpress.org/support/users/grapplerulrich/) did you
   resolve this at all? I’m also experiencing this same issue.
 * So far our best fix has just been to export with Save for web (legacy) instead
   which doesn’t result in the same issue.

 * The only two fixes are either to set `WP_DEBUG` to false or check the exif data
   in the image.
