Canvases

A canvas is one workspace for one image idea. Image Studio's home page is a library of every canvas you can see, and each canvas has a top bar plus a lineage rail that lets you manage the work over time.

The library

Open /images (or click Image Studio in the sidebar). You'll see a grid of canvas cards — each shows the current image, the title, and how recently it was updated.

From the library you can:

• Search — filter by title with the search input
• Open — click a card to enter the canvas
• Use the card menu (three dots on hover) to Rename, Duplicate, Share, Insert into…, or Delete without leaving the library
• Create a new canvas with the + New canvas button

The card thumbnail follows the canvas's currently pinned generation. If a canvas has no generations yet, it shows a placeholder.

The lineage rail

Inside a canvas, the rail on the right is a vertical timeline of every generation, edit, compose, and variation, in the order you made them. Each entry is a thumbnail with a small label for the mode.

What you can do with the rail:

• Pin any entry as the current image — the display switches to it, and your next generation is based on that one
• Hover to see the prompt that produced it
• Open the menu on an entry to remove it from the lineage

The lineage is the canvas's memory. It's why iterating on Image Studio doesn't lose work — earlier attempts are always one click away.

The top bar

Above the display, the canvas top bar gives you the title, the image count, and a row of icon actions:

• Insert into… — drop the current image into another surface (note, wiki, design, assistant, or copy a public link). Disabled until the canvas has at least one generation. See Inserting into other surfaces.
• Download — save the current image to your machine. The file extension matches the source (.png, .jpg, or .webp).
• Share — open the standard share dialog to invite teammates with view, comment, or edit access.
• More — Rename, Duplicate, or Delete.

Renaming

Click More → Rename, change the title, and Save. Empty titles aren't allowed; titles longer than 80 characters trigger a warning. The new title shows immediately in the top bar and on the library card.

Duplicating

Click More → Duplicate (or use the card menu in the library). You get a fresh canvas titled <original> (copy), with the same default aspect and the same brand style attached, but no generations. Useful when you want to start a new direction from the same setup without overwriting the original.

Deleting

Click More → Delete and confirm. This removes the canvas, the parent document, and every generation on it. The action can't be undone — make sure you've inserted or downloaded anything you want to keep.

Sharing

The Share button opens the same dialog as the rest of Opisense — search teammates, set per-person access (view, comment, edit), or toggle public access for a read-only link.

Permissions affect what people can do:

• View — see the canvas and the lineage; can't generate or edit
• Comment — same as view, plus comments on the parent document
• Edit — full access, including running new generations and removing lineage entries

If you're a viewer, the Insert, Download, and Share buttons still work — only mutations are blocked.
