Filter prevents me posting pics

P = %50 so Mavs Pics becomes Mavs%50ics and the filter doesn't care about that and lets it through.
50 is the ASCII code for "P", and the "%" in the URL means treat the next two hexadecimal digits like the letter they stand for instead of taking them literally. You have probably seen a %20 in a URL? That's how they do a space character in a URL, since the ASCII code for a space is hex 20. Same thing here, we're just replacing the "P", which breaks the pattern match for s p i c s, allowing it to be posted.
