Image size

The image shown on the kiosk is taken from Deliverect — the image that was uploaded for the dish or menu item. Because those uploads often have different sizes, in some cases you need to control the scale.

Product images on the r_keeper kiosk look best when they are prepared at a suitable resolution and cropped cleanly. The largest image display area on the kiosk is 512×512 pixels, so use source images of at least that size.

Recommended size

Use images of at least 512×512 pixels. That matches the maximum display size of a product image on the kiosk.

Best practices

• Use exactly 512×512 and crop the images yourself in advance so product photos look consistent across the menu; or
• Use a substantially larger image and fine-tune how it appears on the kiosk with the Deliverect meta tag imgScale.
• Avoid large amounts of white space or padding around the subject. Extra empty area usually means you need more scaling adjustment with imgScale to get a good result.

imgScale meta tag

To change how a product image appears on the kiosk, set the Deliverect meta tag imgScale on the item:

• 1 — no change (default scale)
• Less than 1 (for example 0.8) — smaller on the kiosk
• Greater than 1 (for example 1.2) — larger on the kiosk

The imgScale meta-data value is optional. If it is not set, the image is shown 1:1 as in Deliverect.
