hi
there are various details present in a data string depending on the tools used to create the image.
A digital camera image that is used straight from the camera will have data regarding your camera manufacturer and model & verios camera settings.
If you edit the image in photoshop for example - this will be in the data string, along with the version.
The version of Windows is sometimes in the data string.
The time and date it was taken/edited will be present.
Pictures taken with a new camera or maybe a new phone possibly will have a gps string - giving your exact location (this can be looked up in google maps).
Taking screenshots of your pics then selecting the photo area, will also leave a data string.
There are quite a few variables that can be filled - I'm not going to take the chance - just my personal paranoid persona
All of this can be easily cleaned.
It's not that this alone could link you - but if they are looking (investigating), it's got to be a factor - it would be for me if I worked for them.
