This plug-in will create a link to a single post that was published exactly one year prior to the post currently being viewed. For example, if the post being viewed was published 2011-01-15, the plug-in will create a link to the post published 2010-01-15.

A Year Ago

Creates a link to the post from exactly one year ago. Works only with one-post-per-day blogs and is designed primarily for photoblogs.

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):
<ol>
<li>‘exifize_date’ custom meta (date or ‘skip’)**</li>
<li>EXIF date of Featured Image</li>
<li>EXIF date of the first attached image</li>
<li>Do nothing. Be nothing.</li>
</ol>
**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.

EXIFize My Dates

It does as advertised. The only thing missing is an option do exify a single post. Whenever I post an older image, I have to check ALL the posts, so that's definitly a point of improvement. That says, what it does it does great!

Great tool to sort posts

Photoblog plugin to bulk change the published dates of a selected post type to the EXIF:capture_date of the Featured or 1st attached image of the post …
