test post - possible bbcode bug

[longneck]

ok, this is no longer a test post, so if someone can edit my title, that would be great.

anyway, i realize that my quotes here aren't matched, but can someone explain why this shows up as an html entity code instead of just %s?

foreach ($second_array as $i) {
  printf("<img src="%s">%s</img>"
    , $first_array['$i']['username']
    , $first_array['$i']['avatar']);
}

and now i can't make it happen again. grr...

i'm going to bed.
