The Image Buffer
The Image Buffer keeps the last 9 images of the app: drawings from the Doodle screen and impression boards, A.I. drawings, images made from templates, images arriving from WEB-polling, Send to API or the HTTP socket. You can browse them, send them to your display devices and printers, and use them in image templates.
The full Image Buffer needs the Image Buffer add-on (included in every subscription).
Without the add-on
A.I. images and the images found in WEB-polling / Send to API answers are still kept — but only one image (the newest replaces it), on this phone only. That is enough for actions like save image to phone gallery.
Where you see it
On the Settings page the IMAGE BUFFER card shows how many images are stored, with VIEW, CLEAR and SETTINGS.
- Thumbnail gallery (action open/close thumbnail gallery): a 3×3 grid of the 9 places. Tap an image to open it, long tap to delete it (with a confirmation, if you switched that on).
- Image browser (action open/close image browser): the images full screen — swipe left/right between them, swipe up or down to close.
- show last / previous / next image: steps through the images (wrapping around). On the Doodle screen or the black screen the image appears there too, and every image you step to is also sent to a connected PeekSmith 3 / Apple Watch.
When a 10th image arrives, the oldest one is dropped. The images are also saved to your account on the server.
What goes into the buffer: Image types to save
SETTINGS → Image types to save → Manage decides which pictures are saved:
| Type | Default |
|---|---|
| drawing before erasing (the Doodle screen, when you clear it) | off |
| drawing at recognition (a handwriting sent for text recognition) | on |
| A.I. drawings (OpenAI, Gemini, Lifelike, city drawings, hidden reveal) | on |
| A.I. image prompt results | on |
| images from template | on |
| WEB-polling results | on |
| Send to API responses | on |
| images from HTTP socket | on |
| TrueWrite / TrueSketch images | on |
You can always save the Doodle drawing yourself with the action save doodle drawing to Image Buffer.
Images in WEB-polling and Send to API answers
When an answer contains an image (a picture URL, or image data anywhere in a JSON answer), it is saved automatically — made smaller (max. 1280 px), without duplicates, at most 9 per answer.
Settings
- Sync images from server — Sync now: downloads the images saved to your account.
- Image types to save — Manage: see above.
- Confirmation before delete image
- Stored image quality: 30–80 % (default 30 %). Higher quality = bigger images and slower syncing.
- Clear buffer on app start (on by default). If you switch it off, the buffer is synced from the server when the app starts.
- Clear buffer on ROUTINE START: empties the buffer when you tap START ROUTINE.
- Clear buffer on WEB-polling start

Run an action only at the right moment
Any action can wait for the buffer: "Only if Image Buffer has exactly 2 images". See Triggers and actions → Condition.
Images in image templates
An image template can place Image Buffer images anywhere on its canvas:
| Variable | Meaning |
|---|---|
#IMAGE |
the newest image |
#IMG1 .. #IMG9 |
counted from the oldest |
#LAST1 .. #LAST9 |
counted from the newest |
An image that is not there (yet) is simply left out. More: Image templates.
