What camera and lens?

Hi kriztian ! It depends of you web browser.

For Chrome, I found "EXIF reader" to be convenient (just hover over the picture to get EXIF data in the upper left) :

For Firefox, I use FxIF (but you have to right click, this is forbidden on some sites) ; you get more informations with this one but in a popup window ...

Each browser has a site for extensions with complete informations about versions, and compatibility problems (when you upgrade your browser, you may have to update the plugins).

You'll find a lot of pluggins for your browser (Safari, IE, Opera, ... whatever) with a google search
I guess you may also find something like that for Android and iOS browsers
