What computer do you use? As Will says, there are plugins for web browsers. I'm on a
Mac. If I'm looking for settings, I quickly download the file from the web browser's cache, choose File -> Get Info, and it's all right there. I then delete the files, of course, as it would be rude (and against the copyright law) for me to keep a photo of yours without asking your permission.
By uploading your file to a website, you are essentially giving me permission to download it (that's how web browsers display pictures), but you haven't given me permission to keep it. If I want to do that, I ask.
