Here is another plugin, Lameda, that uses the exif data that comes from the images as uploaded into WordPress. Lets take a picture:
Here is the exif data when you put this tag in your post: [lameda_exif id=556]
The thing with this, is you still have to go into the post html and find out what the wordpress id of the image is. Still a bit of a pain. I like that it is pulling this from wordpress. Looks like wordpress stores this in the post_metadata table in an entry about the image. Not all data is saved, just some of the more basic ones like those shown. We just need a more automated, and visually appealing way to show it.
