From Richard Hall:
There is an add-on for Firefox allowing you to view EXIF data from an image.
I found this as an alternative to using Opanda's EXIF viewing software. It seems to work very well and rather than install yet more software onto a system I like the idea of a nice n small Firefox extension to do the same job.
You can find it here
on the Firefox add-ons page, or here
on the authors website, which may be more up to date with versioning.
