Fixed the problem that Aria2 could not download images after v1.3.4 update.
The new download url has to be used with cookies, so Aria2 wouldn't work. But 'GM_cookie' couldn't get those cookies with 'httpOnly: true' option, so Aria2 couldn't get full cookies to download via the new download url.
Anyway I tweak it to use old 'large url' to download via Aria2. The final images downloaded are the same with different download urls.
