Again, remember that every time you restart Tails you will have to do this again, so get into a habit of doing this every time. You never know when your favorite website could become compromised.
Moving onto meta data. There is a bit of a famous story about an online hacker named w0rmer that would take pictures of his girlfriend and post them online after he would deface a webpage. What he either forgot, or didn’t know was that photos taken with the iPhone and other smart phones save the GPS coordinates of where the picture was taken and store it in the meta data of the picture. Check out this article below.
You need to remove this meta data! Otherwise you could end up in federal prison with w0rmer. Luckily Tails has a solution for this! See why I love Tails?

Please get a more clear idea of how this works by reading the following page.
Please note the currently supported formats. In terms of pictures, jpg, jpeg and png. But unfortunately MAT is not perfect and I wouldn’t solely rely on it, so a better idea would be to never upload pictures of yourself or your significant other online, especially bragging about a hack you committed. Please read the site provided above for more information.
