I have been working on a plugin for WordPress that will display the EXIF data for an image. It turned out to be harder than I thought. First of all, there are very few working libraries that will access the data in an image. Second, this is my first WordPress plugin, and the documentation is not what I had hopped. So‚Ä¶ to start, and get something out there, I have scaled back abit.
The first iteration of the plugin will simple replace the title of the image (displayed on hover) with the some meta data captured by WordPress. This will be things like f-stop and shutter speed. Eventually I would like more data, but I will have to go outside of WordPress to get it. Second, I will need to beef up the display options. Using the title is not what I wanted. I would like to have a hover give a proper note, or a click with a lightbox effect. I will get to those later.
So, the first release of this plugin will be soon. I have it working within the media library, but when you are adding an image, the admin panel uses a pop-up with a different form. I just need to get it working either way.
