Embedding of Ogg Files in Images Blocked

Yet, concatenating any other kind of data to the end of an image (such as a repeated string like "NYO~NYO~NYO~NYO~") is allowed.

I'm guessing it will take about 15 seconds until someone slightly modifies the script and sound image creation process to XOR the oggs with a simple bit pattern.

The discussion on /a/ started getting technical, so I'll defer to /prog/ in hopes that someone already knows the answer to this:

Is it possible to detect when a JPG is done decoding before EOF is reached? Whether or not it is possible to permanently block soundimages is dependent on whether or not this is true.

If it is so, the feasibility of blocking soundimages would also depend on whether a "million lels" attack is possible with a JPG.

By comparison, it should be easy to determine the end of a valid PNG, as there is a special IMAGE END chunk.
