In the latest version of ImageEn 8.0.0, EXIF data is no longer displayed by some camera models. I was able to test the Canon EOS 10D, Canon EOS 500D and Panasonic Lumix DMC-TZ61 cameras.
There is a bug in 8.0.0 if you load images without using their file extension, then EXIF will not be acquired. We'll have a fix in 8.0.1 in the next week or so, or you can email us for updated source.
