I think you're looking for an application that can read the EXIF information embedded in an image. For that there are many available, including some web browser add-ins.
I use IrfanView as my image viewer, and if you install its add-ins you can hit "i" to find a button to display EXIF information. I also just installed some Firefox Add-In that shows EXIF information...I think it is called Exif Viewer (version 1.30), and it seems to work pretty nicely. Cheers.
