Image & asset specs
Exact sizes and formats for every image you can add across OmniLab, with live previews you can download.
Give this page to whoever makes your artwork. It lists the size, shape and format of every image a campaign uses, each with a live preview and a starter PNG to download. Most also have Generate your own, which makes a PNG at the exact size from your text and colours.
Shared visuals
Most experiences reuse the same few visuals. The banner size also covers landing page headers and notification emails.

Specs and images in Studio
Image fields in Studio have See specs, which opens the same specs in an Image specs panel. Most also have Generate, which makes the image there. Here, Lindenhall makes the banner of its landing page, under Banner in Update Header.
-
Beside the field, select Generate.
-
Under Template, choose a design.
Content changes the text and pictures. Your brand holds the logo, colours and font, which start from the campaign's theme.
-
Select Use this image.
The image fills the field and joins your Images & Files library. Where a field can't take it straight away, it only joins the library: select it from there. Download PNG saves it to your computer instead.
In the validation window, an issue caused by a missing image has the same help: Generate the image, or See specs when the image has no generator. 3D models have no generator.
File formats
- Images: JPEG, WEBP or PNG. Icons and the wheel pointer need a PNG with a transparent background.
- 3D objects (catcher, 3D selection, treasure hunts) come from your 3D library, not an image upload. They need a GLB file, plus USDZ for the best result on iPhone and iPad.
