Just read the topic regarding those posts from artstation. Guess one should change the /large/ to /original/ @sweetpe@ @Qpax?
I was just sending private message about this matter while you just made this comment but yeah I guess that's how it works if you want to obtain original image on artstation. Its just how it works with twitter images :large to :orig and in this case for artstation its just /large/ to /original/.
@Little_Nova@Qpax Yes, always and forever use /original/. Except even with this URL the quality is still poor relative to like DeviantArt, Tumblr, and Pixiv are. I always scan all of an artist's accounts.
I'll add a blurb to howto:upload regarding how to upload from ArtStation like I did for Twitter. I'm still strongly in favor of making this stuff automated but I guess we should make it clear to people which URLs to use... Always use the image URL with /original/; always change it to www.artation.com/RestOfThePostURL after upload.
