I now have a first version of CwExif that can be downloaded. This is a new WordPress plugin that will show exif data for an image uploaded to the wordpress library in the title tag. There is a button on the media admin screen that will take the exif data and put it into the title tag. On hover, the data will be displayed.
This is just the first version. There is much more that I want to do with this plugin, but you have to start somewhere.
Get it here.
