Made a userscript version of the dlsite preview loader for those that are lazy and trust random javascript from 4chan. It will try to insert the previews into the page if it detects the error box and will redirect between the announce and maniax pages if necessary. To the anon that made the original there is a small bug, it won't pick the correct folder for codes ending in 000.

I've also started hosting the gallery previewer on github. Local copy no longer needed.
