Installation / Configuration

This is a standard, default module. It is included in the Gallery 3 install, but it is not activated by default.

  1. Activate exif module: Admin > Modules

A new maintenance task will be created to "Extract EXIF data".

  1. Rebuild EXIF data: Admin > Maintenance > Rebuild Exif data

If any modules are installed (and activated) that modify the EXIF information contained within the image (such as autorotate or rawphoto with the exifcopy patch), it may be necessary to install the moduleorder module and change the order of the modules so that the exif module runs last. Otherwise, the EXIF information stored in the database may not match the EXIF information stored within the image.

Notes

This module uses the third party php library "Exifer" to extract/interpret the EXIF information.

This module only processes the EXIF information for images with a a mime type of "image/jpeg" (Reference: helpers/exif.php - exif_Core::extract()). Many other image formats can contain EXIF information.

Not all EXIF tags associated with the photo are extracted. The EXIF tags that are extracted are:
