Jpeg EOF

I'm trying to find out where the JPEG file ends, mainly to find out whether there's any information appended to the end of the file. I've tried searching for the EOF (FF D9), but to my surprise, this is repeated multiple times in the file in 1 out of 5 files.

Is there a way to safely determine where the JPEG file ends?

There can be those sequences inside the JPEG stream besides the tags.

Look, it's not that difficult, you shitbag wannabes.  JPEG is a compression format.  They're not going to put any extra bytes in that can be inferred from elsewhere, nor are they going to bother with adding escape codes around FF D8|D9 pairs just so your lazy ass can grep for them.
