Exif info in Photo Gallery lightbox

When pushing the info button in Wordpress Photo Gallery lightbox there is some information like filename, camera brand, ISO, Aperture Orientation. Now, I am a member of a amateur photographergroup that comes together every two weeks. Every evening there coms the big question: Which shutterspeed did you use? A main part of making a good image is'nt it? Sadly the shutterspeed is not displayed in the infobox. Can you, in any way, make this happen? It would be much nicer to look at all the images knowing there is shutterspeed information availleable. I hope you understand my question.
