- * Modyfikacje pluginu:
- * Dodatkowe parametry:
- * img="bool" - jeśli true, zwraca sam relatywny adres pliku z obrazkiem. Polecany do używania z link="false". Domyślnie wynosi false.
- * square="bool" - jeśli true, obrazk przed przeskalowaniem jest nakładany na kwadrat o wybranym kolorze. Domyślnie wynosi false. Bok kwadratu jest równy długości najdłuższej krawędzi obrazka.
- * square_color="html_color" - kolor kwadratu, na który nakładany jest obrazek przed skalowaniem. Format koloru -sześcioznakowy kod html(bez #). Domyślnie ffffff.
- * Możliwe jest uzyskanie przeźroczystosci, wartość square_color musi wynosić wtedy "transparent".
- * square_margin="int" - margines, jaki będzie dodany do krawędzi kwadratu. Domyślnie 0.
