I think I've fixed this, but do you have an example of "http://view.thespectrum.net/series/SERIESNAME"? All I can find end in .html.
thespectrum.net broken
http://view.thespectrum.net/series/SERIESNAME doesn't work at all.
Clicking next page to http://view.thespectrum.net/series/SERIES.html?ch=Volume+N&page=M only displays one image for what I tested. Displays 2/N loaded when on page 2 etc.
Only exception I found is Berserk Vol. 1, which works just fine.
