About

This projects posts images of iDOLM@STER idols (and one office lady) to Bluesky. It's similar to imas765probot (the bots on Twitter) but with new features and idols!

Compared to imas765probot, there are 4 new bots: Kotori and Dearly Stars (Ai, Eri and Ryo). Also, images that feature multiple idols will be reposted by the respective bots.

For updates on the bots, consider following me on Bluesky.

imasimgbot is separate from imas765probot, and is not ran, affiliated with or endorsed by Kikuflare (the creator of imas765probot).

If you're interested in more details or the history of the image bots, I recommend you check out One year of iM@S Image Bots.

Current status

Most bots post either every hour or every 90 minutes. A few others post less frequently: Ryo posts a few times a day, and Ai and Eri currently post semiweekly. The goal is that bots with enough images will run every hour, much like the aforementioned imas765probot used to.

Support policy

I commit to maintaining the image bots on a best effort basis until further notice. If I decide to shut down the image bots, for any reason, it will be announced at least one month in advance, barring any unfixable technical problems.

Fediverse support

Some of the image bots are available on the Fediverse (the network powering Mastodon among many others) with the help of Bridgy Fed. You should be able to follow the following image bots by searching for their handles from your instance:

• Haruka: @harukaimg.bot.akizuki.best@bsky.brid.gy
• Yukiho: @yukihoimg.bot.akizuki.best@bsky.brid.gy
• Ritsuko: @ritsukoimg.bot.akizuki.best@bsky.brid.gy

If you want to see more of the image bots on the Fediverse, please contact me with the bots you want.

If you're having trouble finding the image bots from your instance, your server admins may be blocking Bridgy Fed, and you'll need to reach out to them for assistance.

FAQ

Q: Will you add other branches/idols?
A: I won't be adding more idols as working with the 16 already running is enough of a pain.

Q: I'm a feed operator and the bots are clogging my feed!
A: The list linked above contains all running image bots, and many feed tools let you mute users on specific lists.

Q: Can you make me bots for x?
A: Managing the 16 bot accounts is already more than I want to do, so no. I encourage you to host this bot yourself, see the Tangled repository for information on how to do that.
While the terminology and internal structure used is iM@S-focused, the bot can be used to post images of literally anything, whether that be pineapples, idols from other franchises like Love Live!, characters from other games like Puyo Puyo or whatever else you can think of.

Q: I need help on hosting this bot!
A: Check to make sure you didn't miss anything in the docs, and then contact me for assistance.

Q: What's the license for the source code?
A: imasimgbot is licensed under the MIT License.

Note

• Similar images are counted as one.
• Many images also feature other idols in addition to the main one. Such images will be reposted by their corresponding bots, so the true number of images per idol is higher.

Roadmap by Priority (archive)

This roadmap is only of historical interest; the image bots are largely complete and there are no major changes planned that would be of interest to users.

These are issues that are relevant to people interacting with the image bots. For technical issues, please see the Tangled repo. Older issues may be in the GitHub repo.

Done

Posts not rendering

On September 28, 2025, recent posts by the image bots stopped loading properly due to network problems. The issue resolved itself on the 30th.

For more information, please see this thread.

Finish removing AI upscaled images from the bots

From the bot's inception, I had unknowingly used AI upscaled images for some bot images. Use of AI upscaled images is against the imasimgbot submission rules.

The plan is as follows:

1. Stop adding AI upscaled images (done)
2. Replace all AI upscaled images in use with the original versions (done) 3. Make the AI upscaled images publicly inaccessible as deletion is not possible (TBD)

As of June 4 2025, no idols are using AI upscaled images, however old posts may still use them.

Birthdays

Scope: idolbot
The idol bot should have a different event when it's the idol's birthday. This requires some metadata about the idol.

Add image dimensions to post record

Scope: bash-atproto
This will fix the image preview thing being incorrectly sized when the image hasn't loaded yet. It's a minor issue but it is one that can be fixed easily.

Fix video uploading

Scope: idolbot
The recent update broke video uploading, so no Mako Mako Rin until this is fixed. Tracked in #2

Independent post scheduling

Scope: imasimgbot.sh, idolbot
The individual idol bots should be able to post at times of their choosing rather than all at once when the master service fires. This could be done by having the master service fire at multiple times and the bots decide when to actually post. This would involve metadata in idol.txt on when to activate or not.

Not done

Proper alt text

Scope: idolbot
Currently, imasimgbot uses the alt text for image origin information rather than using it for actual alt text. What could be done is to move the image origin information into the main body and then write alt text where it belongs.
The issue is that this would require alt text to be written for all images currently in the bot, which currently has over 300 500 1,300+ images.
The amount of time this would take to fully implement combined with the relatively low benefit this would bring makes it low priority. Accessibility is important but I'm not sure if an image bot will attract people that need alt text.
