Display Exif

This plugin instantly adds exif data window on its image. You have nothing to modify your entries to add this feature!

LBell

Update the post dates of your WordPress posts, pages, or custom post types based on the EXIF metadata of your images. Can be done in bulk (via Tools) or one at a time (via Edit Post screen).
Perfect for photoblogs where you want the post date to reflect when the photo was actually taken, rather than when it was uploaded.
The dates will be changed using (in order of priority):
<ol>
<li>Custom date of your choice (date or ‘skip’)**</li>
<li>EXIF date of Featured Image</li>
<li>EXIF date of the first attached image</li>
</ol>
**You can override the function with a custom meta field named: ‘exifize_date’ which accepts: 
 – ‘YYYY-MM-DD hh:mm:ss’ (for example: ‘2012-06-23 14:07:00’) 
 – ‘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

Update Post Dates from Image Metadata (EXIF) in WordPress. Great for photoblogs.
