For sources sending to or received from Tumblr blogs, can we not use direct image links (links like data.tumblr.com/ that send to only an image)? Linking the post on the artist's blog where the image is directly feels better in my opinion, as if you want to find the artist from the source and the artist's page, you're already on it by clicking the "Source" link here on Danbooru. The way I see most people linking to just direct images seems round about as if you wanted to find an image's artist who is on Tumblr, you'd have to back out, go to Tumblr and search their artist handle and hope they go by it on there (maybe they use different handles for different sites). Or go to the artist's page on here and then hope a link to their Tumblr page is on there and that it's up to date. That seems very round about, doesn't it? Sources for Pixiv artists usually link to a page where you can go directly to viewing the artist's entire profile. The main idea I'm having is that linking to just the image makes following (or like contacting for commissioning info or something) that specific artist on those platforms that much more difficult, especially if they use multiple pseudonyms.
