Фейсбок(Facebook) АПИ(API) - за ъплоад на снимки

August 5th, 2008 zetxxx

След дълга липса на писания в този блог поради липсата на свободно време реших да запечатамедин код които ми отне 3 часа от живота и както винаги се оказва проблемът е бил в — ( 2-те тиренца ) :(.

Идеята на този класс е да може някои девел. за напред ако има проблем с ъплоад на снимки в фейсбоок да го види да си го копне - да попълни липсващите параметри и наий-вече да му спести работа :).

Лиценза е гну, държа само да се спомене че е моя работа …

ето го и кода
