How to read picture taken time from JPEG

[Pinal N Patel]

Hello Everybody,

I am building a web page using JSF technology. One of the page has a function to upload pictures into the application and then can be viewed in a thumbnail manner.

My question is realted to Java API not JSF, one of the requirement is to display "picture taken time" along with the picture. Currently, the page displays the time when the picture was loaded as oppose to when the picture was taken. The picture format are usually in JPEG/GIF. Is there a way to retrieve the "picture taken time" from JPEG/GIF file through Java API?

I would highly appreciate any response I can get to complete this requirement.

Thanks in Advance!!

You're looking for so-called JPEG EXIF data. A Java library that can read it can be found here.

That doesn't work for GIF images, though, which simply doesn't include that data. But since GIF is not well suited for photographs it gets rarely used for that. Maybe you can even disallow GIFs?
