I Saw this gallery was only uploaded in French and I found an English version laying on my computer also, a few things to note:
1) These images are about 5 years old by now
2) I didn't typeset or translate this my self I have no idea who did but whoever it was I hope they stay far away from typesetting lol
3) Sadly I couldn't find the first 6 pages in English but it doesn't really matter to the story if you are wondering

Update: Thanks to MJTH for finding a better version I decided to update this gallery to feature the first 6 pages in English and with smaller watermarks! (also it's now a BIT higher resolution)

Bad news for ya... the author did the typesetting lol

Base +6, voxxyn +9, SomeDude44632 +6, AnswerIsAlwayMiata +7, MedHetz +5, Deep in +4, Clanofgators +6, flamincatturd +6, Mongloom67 +4, kimamb +6

Here is a link to a gallery on a different site that has the first few pages in English. As you said they don't really add much to the story, but at least this way you could get a completed gallery here. Also this version of the images has smaller non-author water marks.
