I feel like Sherlock, if he were a developer

Thank you for posting.

That code being written in the first place does not inspire confidence. "strcat" has almost no valid use cases, and the suggested solution of using a fixed-size buffer is likely to lead to further instances of exactly the same variety of error at some time in the future.

> char filename[256];

The sane solution here is to use strncat or another, more appropriate, function such as snprintf. The length of the buffer should at least be a macro rather than a magic number.

Approximately half of the vertical space in the body of the article is occupied by animated gifs!
