WordPress.org

This tool will attempt to irreversably change the actual post dates of all entries in the post type you choose (supports posts, pages, and custom post types).

The dates will be changed using (in order of priority):

1. 'exifize_date' custom meta (date or 'skip')**
2. EXIF date of Featured Image
3. EXIF date of the first attached image
4. Do nothing. Be nothing.

**You can override the function with a custom meta field named: 'exifize_date' which accepts dates: 'YYYY-MM-DD hh:mm:ss' (for example: '2012-06-23 14:07:00') or 'skip' to prevent the EXIFizer from making any changes.
