This page shows a slideshow with photos that generate errors when the exif data is extracted using exif_read_data().
To set up such a situation, install WordPress and plugin WP Photo Album Plus.
Create an album in WP Photo Album Plus.
In the release version all calls to exif_read_data() are preceeded by a @ to suppress errormessages.
Use an ftp program to download/edit/upload file …/wp-content/plugins/wp-photo-album-plus/wppa-exif-iptc-common.php
Remove the @’s.
Now upload the photos you downloaded here to reproduce the errors.
These errors still exist in PHP 7.4.8
The download buttons under the photos will supply you the original .jpg files.
Near the bottom of the display you will see the exif data that has been extracted.
