howto:twitter
Twitter is a website where a growing majority of Japanese artists publish their works. It serves as a secondary source on Danbooru.
This page will describe how to upload from Twitter, in addition to how to handle new artist entries in the case an entry doesn't already exist for the artist you're uploading a work from.
Word of caution
Because Twitter resamples all jpg and PNG images uploaded to the service, uploading from Twitter is sometimes potentially risky as a user without the Unrestricted Uploads permission. You should always look for a better image source off another site such as pixiv or nicoseiga if it is available (help:image source).
Twitter, however, will not resample PNG images with alpha information. PNGs in a RGBA32 colorspace with non-trivial alpha transparency information will simply undergo a round of bad compression. PNGs in an RGB24 colorspace will instead be converted and sampled to JPG.
The only time it is safe to upload from Twitter is if the Twitter upload is considerably higher resolution than an existing image from those sites and has no visible JPEG artifacts or resizing artifacts. An upload from Twitter is likely to go deleted if a better version is uploaded and it is still in the mod queue.
Uploading
1. Upload with the danbooru bookmarklet, or paste in the URL of the work you wish to upload in the upload page. This way, you don't have to upload the image from your computer and risk it being an image sample. If you wish to upload multiple images, use the batch bookmarklet. For more technical details, you may expand the following:
It's important to note that the HTML URL to the tweet is much more preferred than that of the direct image URL to the tweet for various reasons. Artist information and commentary, for example, are readily available to pull from the image source if the tweet has not been taken down yet.
The upload page will NOT always correct your source to the HTML link for you. Remember to correct it yourself when it so happens.
2. Use the artist tag detected under Related Tags, if there is one. If there is none, you may refer to the rest of this article on how to choose an artist name and make an entry for them, or correct their artist entry if they have changed their twitter handle.
3. Remember to tag the rest of your upload and follow the rest of the procedures under howto:upload.
Artist naming
Rule of thumb is: Make a simple, readable, and memorizable tag.
The first choice is to use the artist's real name if you can find it on any websites or blogs listed on their twitter profile. See howto:artist for advice on finding the artist's name on their website.
Most of the time, an artist on twitter will also have a profile on pixiv or nicoseiga. You may check there if it is available. Because Twitter allows users to change either their username or handle with little restriction, this is more often than not a better choice.
But in the case they post only to Twitter, you may go ahead and use whatever name they have available under their twitter account.
Once you have a name, romanize it. Name kanji often have several different readings, so it's best to use any available indicators (such as the twitter handle itself) on how to read the name. If you don't know how to read this name or are unsure of the correct reading, post in topic #8199 to ask for help.
Note that Twitter usernames are not necessarily unique. If it is too generic ("Ken", "Daisuke", "Youko", etc.), add a qualifier to make it unique. Good choices for qualifiers include:
- The artist's circle name
- e.g. gurande_(g-size)
- The twitter handle itself
- e.g. oyamada_(pi0v0jg)
Things to note
- Do not use non-ASCII characters for the artist's name, even if they look like ASCII letters--Ryu is not the same as Ryu. Save that for the "Other names" field.
- Do not use "_(twitter)" or "_(artist)" as the qualifier. There are probably a dozen Twitter artists named Sakura or Miki, so those qualifiers are simply not effective.
- Try not to make a hard to read name like ken_(oooxvbgj).
Artist entries
To create or edit an artist entry, click the '?' next to the artist tag in the tag list. In the artist entry, add:
Other Names
- The artist's Twitter username.
- Any other account names or nicknames on other sites the artist lists in their profile.
URLs
- The Twitter profile URL: http://twitter.com/GK0322
- You may replace the old Twitter handle if the artist has changed it on Twitter.
- The Twitter ID URL: http://twitter.com/intent/user?user_id=12345678
- The benefit of having this link is that it won't change
- You can use the following site to determine a user's Twitter ID: https://tweeterid.com/
- URLs of any other websites the artist lists in their twitter profile.
