These are real renders from the API with the example values in the table below. Switch the size above: the same template lays itself out for all 6 sizes — send size or sizes with the request.
For publishers, photographers, travel and science outreach posting a photo of the day or a photo essay. A long title shrinks to fit, the caption is clamped, and a credit over 36 characters is cut with an ellipsis, since a vertical line cannot wrap. The date is printed like a film camera's imprint, in the order of the render language (10 26 '26 in English, 26 10 '26 in Polish). Without a photo the frame shows a drawn landscape of hills and sun in the accent, so it still reads as a picture. Every frame keeps the photo full-bleed; square and vertical frames give the title and caption more lines, and the story frame keeps the text and imprint out of the platform's top and bottom bars.
Fields
Every field is optional. Long text shrinks to fit instead of overflowing; an image field takes a public URL that we fetch on our side.

For anything more, copy the template into your account: you get an ordinary HTML template with the same fields that you can edit in the dashboard or through the API. If the slug is free on your account, the copy takes it — your integrations switch to your version without changing a line.
