Roshi keeps every image you use so you never have to hunt for the same picture twice. There are two places to work with images: the picker inside the lesson editor, and the shared image collection.

Add an image while you are editing

  1. Add an Image block, or open the image control on a block that has one, such as a dialogue speaker.

  2. Click Image Library. Four filters run across the top:

    • All, everything you can reach, which is where it opens.

    • This Lesson, the images already in the lesson you have open.

    • All My Lessons, every image you have used or saved in Roshi.

    • Curated, the shared Roshi collection.

  3. Search with Search by alt text, then click an image to place it.

Upload your own

  1. Click Upload image at the top of the same dialog and pick a file. The limit is 10 MB.

  2. Fill in Alt text. It is required, and it is also what search looks at later, so describe the picture the way you would search for it: "woman paying at a grocery till", not "image 4".

  3. Save. The image is now in All My Lessons and available in every lesson you write.

Generate one

If you cannot find the right picture, describe it instead. Click Generate image, type what you want, and Roshi creates it. Give it the situation and the people, not just the noun: "two coworkers talking at a construction site, daytime" works better than "work".

Generated images are saved to your library like any other image.

Browse the shared collection

Collections > Images is the full curated library on its own page. Search it by alt text and save anything useful to your own images, so it is there next time you open the picker.

The same picker, everywhere

This is the same library wherever an image is needed, so anything you save once is available everywhere: the lesson thumbnail, an Image block, and the face on a dialogue speaker all open the same picker. See Set dialogue voices and accents.

Good to know

  • Alt text is what makes an image findable later and what a screen reader reads out. It is worth ten seconds.

  • Reusing one image set across a unit of work makes the material feel consistent to learners.

  • Images print. Check Print your lesson if the layout matters for your handout.
