Hmm...maybe i can learning more from you all about my preparation before uploading,especially when i divide doujinshis.
Here is what i do and prepare for uploading doujinshis.

This is kinda interesting but not really something you should put on here as a gallery in my opinion.
It would probably have been better if you just made a thread and and linked to there with your next doujinshi upload.

Hmm...i think so before i upload my preparation photos ,but i think now that there is a option named"NON-H",i think i can make such a gallery for my own;)(only this time) @Astia,oh thanks! i will try it next time!!!

This may be non-h but there are way more mosaics in these pictures.

And I don't think this gallery belongs here either.

doesn't belong on this site.

admirable spirit. i'd recommend u using a sheet of black paper to cover the backside of the scanning pages. thus will reduce the translucent shadow of the back side contents.

This is more a 'stuff I used' than a 'how to do it'. You give almost no instruction, recommendations, sequences/procedures, warnings/suggestions or things of that sort. If someone has to figure out what they're looking at from experience, it's not a 'how to' anymore.
I think properly done this is a good idea, and could be a proper gallery (but I can't say for sure)- but you'd have probably go beyond 'preparation' to showing how to do good scans- maybe with details on scanner qualities desirable, settings in software, post processing- etc.
Regardless- it would probably still be better received in forums first. If it's gallery appropriate I'm sure someone will say so.
Hope I didn't come off as too critical- I'm sincerely hopeful you'll do a better second try!

Would probably be better to put this on the forums. forums.e-hentai.org.
