"Rotate Image?" dialog doesn't offer understandable options

gimp 2.8.10-0ubuntu1, Ubuntu 14.04

1. Open an image containing EXIF rotation data.
2. Try to decide whether to rotate the image.

What happens: You aren't given the information necessary to make the decision.
What should happen: You are given the information necessary.

A dialog appears with a thumbnail and the question: "According to the EXIF data, this image is rotated. Would you like GIMP to rotate it into the standard orientation?" Unfortunately, it doesn't tell you what "EXIF data" is, or what the "standard orientation" means. Most importantly, it doesn't tell you whether the thumbnail represents the image before or after the rotation it is suggesting!

One way of fixing this bug would be to redesign the dialog to be dominated by two thumbnails, one before rotation and one after, and let you click on the one you want.

Another way would be to not put up the dialog at all, and instead rely on you to use Gimp's normal Rotate function if you need to.
