I suggest doing a scan with your anti-virus software to see if it flags anything.

You can use exif_read_data function to get the details for the image and see if there is anything wrong there. Usually, it is base64 encoded so just decode it and see what is contained. Basic server configuration should help you preventing running unauthorized eval function. For the browser, there is not much you can do, the users need to update their browsers to have protection against this.

And I found this with searching 'exif_read_data'.
