They are called Exif metadata, and can contain geotagging informations.

About their support, I've just read that only .JPG, .TIF and .WAV files can carry them, while they're unsupported on files like JPEG 2000, PNG or GIF.

All the info is in the image metadata. You can turn it off in your camera or phone settings. And don't some image hosts like imugr strip images of all this stuff when you upload them? Maybe try that for extra security. And who was this member? Maybe it's related to the hack?

I haven't tried it out myself, but my friend told me if you crop your photo (and save as a new pic) then all the metadata is lost.

It all depends from the software you are using: it may or may not keep the exif in the new file. Sometimes the software could also save additional infos in your new file.
Beside that, often there're settings in the software where you can choose how it must treat these data.

Yeah, I believe that imgur and sites like facebook etc all strip EXIF data for security. Posting raw images is dangerous unless you first strip the EXIF data that contains the metadata.

Sites like facebook, compress images to save memory resources while making it safer for public use.

There is software that can strip metadata from image files. Google for it and you will soon find plenty of freeware that can do it.
