EDIT:
I want to apologize because this is a FALSE ALARM. As others have stated, the browser does automatically when you inspect an Image element. The same happened to me on BlackBank and Nucleus. It's not the market trying to get any information. I saw the popup notification and freaked out. It is my fault and this is a false alarm. I'm an idiot. I'm sorry to any damage I might have done to the community and the Abraxas marketplace.
