I just took the Iron Maiden picture file from the post (75KB)
Embedded it in a file
Extracted it to the file "iron maiden.jpg"
Here is the result:
all of them have 75KB ...
So what about the audio file? As apparently exchanging pictures does not really lead to a solution.
Edit: downloading the DGeneration picture leads to a file with the size of 77KB ... only the pictures do not seem to do the trick.
