Special characters in the EXIF data confuse wp_get_attachment functions

Digital cameras often put special characters in the EXIF data of their images (e.g. German "Umlaute"). After uploading such images parts of this data are put into the database.

Afterwards the function "wp_get_attachment_thumb_url" will return the URL of the full-size image, instead of the thumbnail.

  • Keywords iptc added

The second attached image (no_thumb_no_middle.jpg) contains no EXIF data, only a single IPTC entry featuring a copyright symbol (a not so unrealistic scenario).

After uploading, a thumbnail- as well as a middle-sized image are created.

But "wp_get_attachment_image($imageid, 'medium', false)" will only return the full-size image, thus breaking all layouts.
