## Good to know

- You choose one blog when you connect, and scheduled posts go to that blog.
- Blank lines in your text become separate Tumblr text blocks.
- When Tumblr’s daily post or upload limit is reached, PostQueen tells you plainly.

## Tumblr questions, answered.

Anything else? Write to [support@postqueen.ai](mailto:support@postqueen.ai) and a person answers.

### Which Tumblr blog do my posts go to?

The one you pick when you connect. After you sign in to Tumblr, PostQueen lists your blogs and you choose where scheduled posts go.

### How many images can a Tumblr post have?

Up to 30 images with alt text, plus one MP4 video if you want. Tumblr limits video uploads to 500 MB and 10 minutes.

### Can I add tags and a source?

Yes. Every post can have a title, a link, a source URL and tags. Tags are sent exactly as you type them in the tags field.

### Can my AI agent post to Tumblr?

Yes. Add PostQueen to your AI agent through the MCP server or the CLI and ask for a post to your Tumblr blog, with images, a title, a source and tags.

### Can I save a Tumblr post as a draft?

Keep it as a draft in PostQueen while you work on it. Once you schedule it, it is published to your blog at that time; Tumblr’s own drafts and queue are not used.
